What is the purpose of a Strategic Highway Safety Plan (SHSP)?
Each state is required to have a SHSP, which
includes engineering, management,
education, enforcement, and emergency
service elements of highway safety as key
factors in evaluating highway safety
projects.

How does the condition of the roadside potentially increase the chances of a crash?
• A roadside with numerous fixed objects
and/or steep side slopes means that the
vehicle will strike something or roll over
before it can be stopped or re-directed.
• A safe roadside allows the driver to safely
stop the vehicle or get back on the
roadway.
