A new survey from the AAA Foundation for Traffic Safety found that more than 90% of drivers reported slowing down or moving over the last time they passed a disabled vehicle, tow truck or police vehicle on the shoulder.
However, previous observational research found that only 64% of drivers actually changed lanes or reduced their speed when required. More than one-third (36%) did neither.
The consequences of failing to slow down or move over can be deadly.
More than 2,100 people were struck and killed while stranded or working at the roadside between 2019 and 2023. In 2025 alone, AAA responded to more than 30 million roadside events, and 15 roadside service providers lost their lives in slow down, move over-related incidents. Several of those crashes involved impaired or hit-and-run drivers.
“Drivers often think roadside danger only affects police officers, firefighters and tow truck operators,” Nick Jarmusz, director of public affairs for AAA. “But anyone can become vulnerable at the roadside. A flat tire, dead battery or mechanical problem can place drivers and passengers just feet from moving traffic. That’s why slowing down and moving over is so important.”
A new AAA survey found that drivers understand the risks of being stranded at the roadside. More than half (55%) of Wisconsinites said being struck by another vehicle would be their biggest concern if their vehicle became disabled.
“It’s easy to think a roadside stop is someone else’s problem,” said Jarmusz. “But every driver could end up in that situation. That’s why slowing down and moving over is more than a legal requirement. It’s a responsibility we share.”
Recognizing the dangers faced by stranded motorists, many states have expanded their slow down move over laws to include disabled vehicles and other roadside situations.
All 50 states have laws requiring drivers to move over or reduce speed when approaching vehicles stopped on the roadside. However, the specific vehicles covered and speed requirements vary by state.
In Wisconsin, drivers must move over for all stopped vehicles displaying flashing or hazard lights, including law enforcement, EMS, fire, construction and people with disabled vehicles. If changing lanes is not possible, motorists must reduce speed and proceed with caution.
“Most drivers never expect to become the person stranded on the shoulder,” Jarmusz said. “But breakdowns happen every day. The safest thing you can do is create as much space as possible between yourself and moving traffic and call for help.”
