Study Finds Vehicle-Mounted Safety Signs Are Effective at Reducing Roadside Collisions

NASHVILLE, Tenn. — AAA-The Auto Club Group continues its “Move Over for Me” campaign, by sharing a new study that examines the risk of being on the roadside and the effectiveness of various tools designed to alert approaching drivers.

AAA’s Research:

The AAA Foundation for Traffic Safety conducted two field studies on busy roads to determine the effectiveness of various countermeasures like vehicle-mounted variable message signs (VMS), cones, flares, and more. The Foundation determined that VMS was very effective.

With VMS activated, drivers changed lanes and slowed down more than when the VMS was not operating. The odds of a vehicle moving over were 95% higher when the VMS was used. Passenger vehicles were more responsive to the VMS than trucks or buses, although both were more likely to move over when VMS was active than when not.

Other Countermeasures have Merits

The Foundation examined cones, flares, and emergency flashing light patterns. Researchers found these led to significant lane shifts by drivers but were less effective at reducing speeds or increasing the distance to the passing vehicles that did not change lanes.

Recommendations

The results from these field studies suggest that using VMS, nighttime light patterns, cones, or flares can positively impact the behaviors of passing motorists under most circumstances. AAA strongly recommends service vehicles or fleets utilize these features, to protect these roadside heroes.

Advocating for Stronger Laws in Tennessee

Currently, all 50 states require drivers to move over for first responders and tow trucks. Yet only nine states have a law requiring drivers to move over for a disabled vehicle with their hazard lights on. AAA is supporting HB 92/SB 201 in Tennesse which would strengthen the current Move Over law. Adopting would help prevent a tragic trend. Nationwide, nearly 350 people are struck and killed outside a disabled vehicle each year.

“The roadside is equally dangerous for a driver with a flat tire, or the person called in to change it,” said Cooper. “While we’re strong advocates for laws that protect tow truck drivers and first responders, AAA believes everyone should be afforded the same protection. Expanding the law would tell drivers to make it a habit to move over anytime they see someone on the roadside. That would save lives, plain and simple.”

 

Examining the Dangers for Tow Truck Drivers and First Responders

Helping stranded motorists on the side of the road should not be one of America’s most lethal jobs, but it is. On average, two emergency responders, including tow workers, are struck and killed every month by a driver who fails to obey the law by moving over to an adjacent lane and allowing the roadside rescuers the space to operate, according to the Bureau of Labor Statistics. Roadside crashes are notably deadly for tow workers. Government data shows that tow operators are killed at a rate of almost 43 deaths per 100,000 workers, compared to just three for all other industries.

As part of its research, the Foundation also surveyed tow workers, emergency responders, and road maintenance workers on their experiences with roadside jobs. Of those surveyed, 60% had experienced a near miss while working at the roadside, while an astonishing 15% had survived being hit by a passing vehicle.

“These heroes put their lives on the line every time they help someone on the roadside,” said Cooper. “We ask that drivers minimize distractions and constantly pay attention to the road ahead of you. Doing so could save a life.”
