Changeable, electronic, or dynamic message signs are used to provide real-time traffic information to drivers while en route to their destination. Many agencies also use these signs to display safety messages when the signs are not being used to display other traffic information. These types of messages encourage safe driving behaviors such as wearing seat belts and not drinking and driving.

The TRB Behavioral Traffic Safety Cooperative Research Program's BTSCRP Research Report 3: Behavioral Traffic Safety Messaging on Variable Message Signs provides an evidence-based approach to help guide behavioral traffic safety message design and display on variable message signs.
