2-302-30
REVIEW
Name some common challenges to improving road safety.
• Limited budget and resources
• Inadequate crash data
• Lack of coordination between
departments/staff
• Limited understanding of safety issues
• Limited training
• Politics

REVIEW
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.
2-322-32
REVIEW
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.
