BATON ROUGE - Gov. John Bel Edwards, highway officials and law enforcement agencies are promoting Louisiana's "move over" law.

The law requires motorists to change lanes, if possible, when approaching emergency or police vehicles on the shoulder of a highway, or to at least slow down. The law is aimed at keeping emergency responders safe from injury. Violators can face a fine up to $200.

State officials Monday held a press conference aimed at reminding drivers about the law, as part of Traffic Incident Management Awareness Week.

Edwards said his uncle, a state trooper who was responding to an accident, was killed by a truck driver who did not slow down or move over. The governor says more than 150 law enforcement officers have been killed after being struck by vehicles since 1999.
