Description:

Speed legends help indicate the speed limit of a roadway. They bring additional awareness where signage may not be posted or where a speed limit change occurs. Field verification is needed to determine if application is justified; no additional data or engineering design is required.

Advantages:

•    Heighten awareness of roadway speed limit.

•    Low cost and fast to implement.

•    Uses a standard traffic control device easily recognizable by motorists.

Disadvantages:

•    Requires periodic maintenance/increased maintenance costs.

•    Does not physically restrict vehicles from speeding.

•    Cannot be used to change a roadway’s speed limit.

•    Does not necessarily result in a change in driver behavior.

Suitable:

All Road Types
