The PA 'Steer Clear' Law requires drivers to move over or slow down when they encounter an emergency scene, traffic stop, or disabled vehicle. This law will help prevent injuries and save lives, but only if drivers follow the law.
Pennsylvania Vehicle Code, 3327. Duty of Driver in Emergency Response Area
When approaching or passing an emergency response area, a person, unless otherwise directed by an emergency service responder, shall:
pass in a lane not adjacent to that of the emergency response area if possible, or:
if passing in a nonadjacent lane is impossible, illegal or unsafe, pass the emergency response area at a careful and prudent reduced speed reasonable for safely passing the emergency response area.
Violators commit a summary offense. Penalties include a fine of up to $250 for a first offense, $500 for second offense, and $1,000 for third or subsequent offense. Repeat offenders may have their license suspended, and violators who cause bodily injury or death of an emergency service provider face additional fines up to $10,000. In addition, fines for several traffic violations are doubled when committed in an emergency response area when first responders are present.
