PHOENIX – Football and traffic safety might not appear to have much in common. But the two converge at a critical connection: protection.

Consider that the safety gear worn by football players has the same purpose as a seat belt – help the wearer survive a violent collision.

So, it's no surprise that the Arizona Department of Transportation and Arizona Cardinals left tackle and Captain Jared Veldheer have partnered to promote the importance of wearing a seat belt with the Seat belts. For life. campaign. On Arizona roadways in 2015, there were 258 unrestrained occupant fatalities, which accounts for 29 percent of the people killed in traffic crashes that year. Lack of seat belt use is annually one of the leading factors in traffic deaths.

"I wouldn't play football without wearing a helmet and shoulder pads, and I won't drive my truck without wearing a seat belt," Veldheer said. "Being safe is being smart."

For the Seat belts. For life. campaign, two public service announcements were produced – "Strong Man" and "Safety Gear" – and each has a 30- and 15-second version. The PSAs can be viewed at azdot.gov, ADOT's social media channels – Facebook, Twitter and YouTube – and will also appear on television during the fall, thanks to ADOT's relationship with the Arizona Broadcasters Association.

ADOT is excited to partner with Veldheer and thanks him for volunteering his time for the Seat belts. For life. campaign. Working with the seven-year NFL pro on the subject of seat belts is a natural fit. His left tackle position protects the quarterback's blind side the same way a seat belt provides security against the unknown for vehicle occupants. In the past five years on Arizona roadways, there have been 1,205 unrestrained occupant fatalities.

"Buckling a seat belt is the easiest thing to do when you get in a car," ADOT Director John Halikowski said. "Its sole purpose is to help you survive a crash. Let the seat belt do its job – buckle up."

"More than one in 10 Arizonans don't wear a seat belt," added Alberto Gutier, director of the Governor’s Office of Highway Safety. "Needless tragedies continue because people aren't wearing a seat belt and parents need to make sure their children are properly restrained, too."

It is no secret that Arizona is known for its intense summer heat and dry climate. But what makes the deserts of this state so hot while states in the eastern half of the country with similar elevation and latitude are distinctly cooler?

For example, the all-time record high temperature for Phoenix, AZ is 122 degrees. But if we travel east to Atlanta, the highest temperature recorded is 106 degrees, and summer average high temperatures peak around 90 degrees.

To find the cause of this disparity, we can turn to the topography of the land in North America that shapes the distribution of moisture in the atmosphere. There are several factors that prevent moisture from reaching the Southwest, including Mexico’s large, rugged land mass, lack of evaporation in the eastern Pacific Ocean due to cool water temperature and mountains that run parallel to the West Coast.

City Latitude/Elevation All-time record high Temp °F Max average High temp °F Annual Precipitation (in)
Phoenix, AZ 33°N, 1106 FT 122 106 7
Atlanta, GA 33°N, 96 FT 106 89 50

How these factors work together to keep Arizona dry

Understanding how these factors keep Arizona so dry requires a little knowledge about how air flows around a low pressure system. The air adjacent to a low pressure system flows counterclockwise, and weather systems generally move from west to east for most U.S. locations (this changes during the Arizona monsoon). This means when a storm system approaches a specific location, the winds initially blow from the south, and this is the direction where the system picks up any available moisture to produce and-or enhance precipitation.

Let's compare the available moisture for low pressure systems that approach Arizona with those that pass through Georgia. Directly south of Arizona is the very large land mass of Mexico with very rugged terrain, while south of Georgia is the Gulf of Mexico, which supplies a lot of water vapor that can be converted into precipitation. In addition to this, Arizona receives little moisture from the west due to the rain shadow effect caused by mountains in California. This explains why Atlanta summers are much wetter and cooler than Phoenix despite similar latitude and elevation. The average relative humidity map below illustrates how topography reduces moisture in the western United States.

US Relative Humidity

Why does Arizona’s dry climate produce such hot temperatures?

One obvious answer to this is the lack of cloud cover in arid climates compared to their humid counterparts, and cloud tops that reflect a significant amount of the sun’s energy back into space so surface heating is reduced. Moisture in the air and ground also slow down the heating process because a portion of the sun’s energy is absorbed by the water vapor in the atmosphere or is spent on evaporating the water in the ground. As a result, as moisture decreases and surface heating increases. Even though the Arizona desert receives the same amount of solar energy as locations in the eastern third of the country with similar latitude and elevation, temperatures routinely exceed 100 degrees because the lack of moisture efficiently heats the ground and air.

Tips to prepare your vehicle for the extreme Arizona heat

Now that you know some of the reasons for Arizona’s extreme heat, we want you to be prepared before you hit the road this summer.

  • Check tires for worn down tread and dry rot. Replace them if necessary.
  • Be sure tires are inflated properly. Remember: Too much air pressure is just as bad as too little.
  • Check fluids often and be sure the cooling system is in working order.
  • Change the oil and be sure to have the proper oil weight for extreme heat.
  • Replace any belts or hoses that have cracks and-or dry rot. If hoses are soft to the touch, they most likely need to be replaced.
  • Be sure the car battery is charging properly.

Editor's Note: ASU’s School of Geographical Sciences & Urban Planning has partnered with ADOT to place graduate-level meteorology students in the ADOT Traffic Operations Center. This allows ADOT to have better information about weather conditions and more quickly determine how to deploy crews and communicate with the public.

Star Trek-themed transportation safety messages

July 21, 2016

By Doug Pacey / ADOT Communications

Boldly go where no one has gone before this weekend on Arizona highways and you will see Star Trek-themed safety messages on overhead signs.

They read:

DRIVE SOBER
LIVE LONG
AND PROSPER

SCOTTY CAN'T
BEAM YOU UP
SO DRIVE SAFELY

The Arizona Department of Transportation’s safety messages coincide with the film release of Star Trek Beyond and the 50th anniversary of the television series. The messages speak to the highly illogical choice to engage in dangerous driving decisions, like driving drunk. Alcohol was a factor in the deaths of 295 people killed in traffic crashes last year in Arizona.

Uninformed people might think they’re OK to drive after having a couple drinks in couple hours, believing their blood-alcohol content is below the legal limit of 0.08 percent. Yet, as Spock says in “Space Seed,” Season 1, Episode 22 of Star Trek, “Insufficient facts always invite danger.”

Consider this fact: Two drinks in two hours might leave your BAC below 0.08 percent – depending on your body type – but it can still impair driving ability and earn you a DUI. In Arizona, which has some of the strictest impaired driving laws in the country, you can receive a DUI if a police officer observes erratic driving and finds that your BAC was below 0.08 percent. Don’t give an officer a reason to say, “Sensor readings are off the scale, sir!”

Don’t make driving a Kobayashi Maru Test. You can beat that no-win scenario by driving sober. Make logical driving decisions and you will “live long and prosper.”

Highway Sign: Pokemon Go is a No-Go when Driving.

By Caroline Carpenter / ADOT Communications

You’ve heard you shouldn’t drink and drive, but now we’re telling you not to “catch and drive.” Pokémon Go, the latest gaming craze, has people of all ages on the hunt for Pikachu and other Pokémon characters.

When the virtual world meets the real world, you need to remember to be street smart. That means, don’t drive while playing Pokémon Go. ADOT has teamed up with the Arizona Department of Public Safety to remind drivers to game safely and avoid distracted driving.

We’re getting the message out using overhead highway signs like the one pictured above and sharing the message on social media. We hope you’ll also share the message with your fans and followers.

We also appreciate the media helping spread the word that Pokemon and driving don’t go together.

Distracted driving is a serious problem across the nation and contributed to 33 deaths on Arizona’s roads last year. In 2015, it was also a factor in nearly 8,000 crashes in our state.

PHOENIX – In the past 10 days, two people working on state highways have been hit and killed by vehicles. These unnecessary and avoidable tragedies illustrate the need for drivers to pay attention in work zones and to give a safe margin of space to vehicles with flashing lights, such as tow trucks and emergency responders.

To remind drivers of the importance of paying attention to their surroundings, ADOT will display the following message this week on overhead signs statewide:

 

2 ROAD WORKERS
KILLED THIS MONTH
DRIVE ALERT

 

When traveling in work zones, drivers should expect the unexpected, as normal speed limits may be reduced and people may be working in the road. They also should slow down, keep a safe distance from the vehicle ahead and pay attention. Minimizing distractions could save a life.

Not only is it a safe practice to give space to emergency response vehicles, such as ambulances, fire trucks, tow trucks and highway maintenance vehicles, it’s also the law. Arizona’s “Move Over” law requires motorists to move over one lane – or slow down if it is not safe to change lanes – when driving by any vehicle with flashing lights pulled to the side of the roadway.

Early Monday morning, a passenger car struck and killed an employee of a contractor working on an ADOT project as he removed barricades from Loop 101 Pima Freeway in Scottsdale. Earlier this month, a box truck hit and killed a tow company driver responding to a stalled vehicle on Interstate 10 near Benson.

PHOENIX – Don’t let a mortarboard be the last hat your young driver wears.

If historical trends hold, the square covers tossed in the air at commencement ceremonies could be the last caps worn by some recent graduates.

That’s because alcohol-related crashes involving drivers ages 16-24 spike in May, making it one of the most dangerous months for young drivers. Since 2010, during the month of May there have been 50 alcohol-related fatal crashes involving young drivers on Arizona roadways, according to data collected by the Arizona Department of Transportation.

Everyone with a diploma knows the solution: don’t drink and drive. Designate a driver. Call a cab or rideshare service. Besides being life-threatening to drivers, passengers and innocents that share the road, a DUI is a terrible graduation gift.

In an effort to discourage drinking and driving among young drivers – and as a reminder to drivers of all ages – many of ADOT’s overhead signs throughout Arizona will display the following message this weekend:

GRADUATES:
SHOW YOUR SMARTS
DRIVE SOBER

Crashes of all kinds involving young drivers typically peak in October and November. But the largest totals of alcohol-related crashes involving young drivers are in March and May. Many variables contribute to this, but spring break and end-of-the-school-year celebrations are obvious factors. Impaired driving crashes involving young drivers occur at higher-than-average rates during the months of June and July, too.

Wrong-way driving.

No issue has prompted more people to contact ADOT over the past year. We have received hundreds of emails, calls and letters expressing concern that some drivers – almost always impaired by alcohol or drugs – are able to drive onto a freeway going in the wrong direction.

People are outraged that innocent motorists driving in the right direction are injured or killed in crashes with vehicles going the wrong way. We are too.

Those who reach out often ask what ADOT is going to do to stop wrong-way drivers.

We answer that ADOT has taken significant steps to address wrong-way driving and continues to seek ways to reduce the threat. Safety is our top priority in everything we do.

Our crews have installed larger and lowered "Wrong Way" and "Do Not Enter" signs in better view of drivers at dozens of highway ramps. We have added attention-getting wrong-way pavement arrows outlined by bright red reflectors on freeway ramps. We are testing wrong-way vehicle sensor technology that could be used to alert motorists, state troopers and other emergency responders to a driver going the wrong way.

Many of those contacting ADOT say we should install tire spike strips to blow the tires of wrong-way vehicles. You’ve probably heard the loud clank as you’ve driven over these spring-loaded spike strips at rental car parking lots and other places where vehicles are prevented from driving in or out for security reasons.

As enticing as that idea seems, there is no place in the world where spikes are used on highway systems. Other states have studied the possibility and determined that spikes wouldn't work, including a detailed engineering analysis by the Texas Department of Transportation that found:

  • Spikes are designed for slow speeds/low-volume traffic and are not guaranteed to damage the tires of vehicles traveling at higher speeds.
  • Broken spikes can damage tires of vehicles traveling in the right direction.
  • Right-way drivers can create unsafe situations by slowing down quickly for spike strips.
  • Spikes can be a hazard to motorcycles and small cars.
  • Spike strips are slippery when wet and prone to getting clogged with dirt and snow.

ADOT appreciates all the feedback we have received on wrong-way drivers. This kind of engagement is what we want to have with you, our fellow motorists.

Safety engineering can only do so much. Most cases of wrong-way driving are a direct result of impaired driving, and to truly address the danger everyone must focus on making better decisions before getting behind the wheel.

PHOENIX – Drive. Just drive.

That’s the message the Arizona Department of Transportation is sending to those behind the wheel during National Distracted Driving Month.

Distracted driving kills thousands and injures hundreds of thousands in the United States each year. In 2015, at least 36 people were killed on Arizona roadways because of distracted driving. Those numbers are too high. Bringing them down is simple.

Just drive.

Keep your eyes on the road, hands on the wheel and mind engaged with driving. After all, your life is in your hands, so keep them free of distractions.

“Think about the last time you shook you head in wonder about a distracted driver killing or maiming innocent people because of the driver’s crazy-stupid behavior,” ADOT Director John Halikowski said. “Please don’t be one of those people standing in front of the judge, facing prison and apologizing to a broken family about how you wish you could take it all back. Just drive and be part of the solution to bring the fatality numbers down.”

Distracted driving comes in many forms: eating a fast-food burger, applying mascara, smartphone use, toggling through a navigation system, twisting your neck toward the backseat to break up a sibling squabble and more. Yet, none of these activities are a driver’s primary responsibility as the operator of a one-ton, two-ton or heavier vehicle and each distraction makes a driver up to four times more likely to be involved in a crash, according to research cited by the Federal Highway Administration.

Just drive.

In 2015, nearly 8,000 distracted drivers were involved in crashes on Arizona roadways, according to preliminary data collected by ADOT. The data shows that young drivers (ages 16-24) engage in distracted driving at higher rates than older drivers, accounting for a third of all drivers engaging in distracting behavior that caused a crash.

Those startling and unnecessarily high numbers tell us one thing.

Drive. Just drive.

PHOENIX ‒ With the weekend forecast calling for gusty winds along with the possibility of snow in higher elevations, motorists should be on alert for adverse weather including blowing dust and limited visibility, according to the Arizona Department of Transportation.

Even though monsoon season hasn’t started, blowing dust is possible throughout the year. ADOT’s safety tips for blowing dust, available at PullAsideStayAlive.org, include:

  • Avoid driving into or through a dust storm.
  • If you encounter a dust storm, check traffic immediately around your vehicle and begin slowing down.
  • Pull off the roadway as soon as possible; don’t wait until poor visibility makes it difficult to do so safely.
  • Completely exit the highway if possible, away from where other vehicles may travel; don’t stop in a travel lane or in the emergency lane.
  • Turn off all vehicle lights, including emergency flashers.
  • Set the emergency brake and take your foot off the brake.
  • Stay in the vehicle with seat belts buckled and wait for the storm to pass.

Along with wind gusts and dust, drivers may encounter snow and icy roads in the high country, especially above 6,500 feet from Flagstaff through the Mogollon Rim. Motorists in these areas should leave prepared for winter conditions and pack an emergency road kit, including essential items such as a fully charged cellphone, food and water, and warmer clothes. For more winter driving tips, visit azdot.gov/KnowSnow.

PHOENIX – Flashing orange lights. Bright orange traffic cones. Striped barrels and barricades.

You’re entering a work zone.

What coincidental timing, too, because the Arizona Department of Transportation is marking the beginning of National Work Zone Awareness Week (April 11-15) today.

After slowing and merging near the start of the work zone, there’s the flagger with a stop/slow paddle and a fluorescent reflective vest strapped across his chest. Expertly moving traffic safely through the work zone all day, obey this person’s instructions – as ADOT’s work zone safety message declares, “The Vest Knows Best” – because lives, including yours, depend on it.

Up ahead, see that maintenance crew? The highway is their office, so please slow down and focus on the road. This ensures a safe work space for them and keeps you safe, too. That’s especially important because, statistically, motorists are far more likely to die in a work zone crash.

According to the Federal Highway Administration, drivers and passengers accounted for 82 percent of work zone fatalities nationally in 2014, the most recent year with complete data. In Arizona, the number of work zone deaths fell to 11 in 2014 after peaking at 17 in 2013. Despite this decrease in work zone fatalities, there is room for improvement

To achieve that, in conjunction with National Work Zone Awareness Week, ADOT is launching a work zone safety campaign, “The Vest Knows Best,” to protect motorists and those who build and maintain Arizona’s highways. Follow these tips when traveling through a work zone to keep everyone safe.

  • Pay attention: Observe and obey posted warning signs, as well as flaggers. You can be cited for disobeying a flagger’s directions.
  • Expect the unexpected: Speed limits might be lowered, travel lanes could be narrowed or eliminated and people may be working near your travel lane.
  • Slow down: Speeding is one of the leading causes of work zone crashes.
  • Merge safely: Do it early and carefully or as directed by signage instead of barging into a line of vehicles at the last moment.
  • Don’t tailgate: The most common crash in a work zone is the rear-end collision. Don’t follow too closely and, again, slow your speed.
