CRASH TYPE ENGINEERING ENFORCEMENT EDUCATION / OUTREACH
Shoulder, edge line, and centerline rumble strips,
wider and brighter striping Increase patrol at nighttime Employer programs
Street lighting
Use Selective Traffic Enforcement Program (STEP)
grants -STEP-WAVE and STEP-COMP Grants Awareness and public information campaigns
Improve infrastructure and roadways to reduce
the number and severity of crashes (wide edge
lines, crosswalks, signage reflectors, markings) Graduated driver licensing (GDL) for new drivers
Employer programs- – Safety apps for company
vehicles and employee vehicles
Increase enforcement of existing laws Awareness and public information campaigns
Screening and testing of elderly drivers and
restrictions Peer-to-peer education campaigns
Educate the consumers, parents, and the public
with age-specific messages, disseminate laws
Re-education and periodic updates for elderly
drivers
Peer to Peer campaigns for teens
Increase enforcement of existing lawsEmployer programs – Safety apps for company
vehicles and employee vehicles
Use Selective Traffic Enforcement Program (STEP)
grants -STEP-WAVE and STEP-COMP Grants
Encourage using technologies such as cell phone
blockers, cell phone disabling devices, voice-to-
text etc. to eliminate using cell phones, other
mobile devices and texting while driving
Identify and disseminate model distracted driving
policiesAwareness and public information campaigns
Conduct education on the risks of distracted
driving using evidence-based strategies to create
a culture of traffic safety
Promote insurance and other incentives for safe
driving
HAND-HELD CELL PHONE USE
WHILE DRIVING (TEXTING,
SENDING EMAILS, TALKING,
ETC.)
NIGHTTIME, DROWSINESS
DISTRACTED PASSENGERS -
TEEN, OLDER ADULTS, NEW
DRIVERS
SPEEDING CRASH COUNTERMEASURES
CRASH TYPE PLANNING / ENGINEERING LAW / ENFORCEMENT EDUCATION / OUTREACH
Traffic calming measures
Deterrence through regular traffic law
enforcement
Institute a regionwide speed-management
outreach initiative
Roundabouts Publicized enforcement periods
Personal communications and messages
through signs, flyers, community outreachReduce number of lanes (road diet) Aggressive driving laws Roadside messagesTurn bay lanes Increase penalties Speed monitoring trailer
Entrance and exit ramps
Different types and levels of penalties for
violations of laws
Pre-tested campaign messages to the target
audience
Advance warnings (signs, markings, rumble
strips)
Collaborate with law enforcement on the use
of crash data for targeted enforcement
Leverage data for targeted messaging to
groups and geographiesEncourage cities to implement temporary
demonstration of safe design speed projects
in various land use contexts
Disseminate Vision Zero information as
related to speeding, and encourage cities to
adopt a Vision Zero policy and program
Targeted speed limit considering below
instead of 85th percentile speed (NACTO
Guidelines, ITE Urban Thoroughfares report):Road designVulnerable usersTraffic operationsWork zonesLand use and Context
Encourage company policies with speed
regulatory system for commercial vehicles

CONTROL PREVENTION EDUCATION / OUTREACH
Continue using Selective Traffic Enforcement
Program (STEP) grants -STEP-WAVE
Encourage programs for alcohol problem
assessment and treatment Control and monitor alcohol sales
Mass media campaigns to inform people
about dangers of driving while impaired
Use a data driven approach to optimize areas Monitor repeating offenders
Increase alcohol taxes and restrictions on
consumption
Educate young drivers through classroom,
news media, advertisements
Enforce Administrative License Revocation or
Suspension (ALR/ALS)
Enforce restrictions on license (courses,
interlock ignition license and suspension, etc.)
Provide and promote alternative
transportation options such as taxi, bus, rail

Develop and maintain data to identify
correlations between impaired driving
incidents and Alcohol Beverage Control
licensing data by road type, corridor, county
and region
Increase penalties for test refusal, high Blood

Create local task forces to identify local
actions
Educate the police, community leaders,
public, and traffic safety partners on the role
of regular traffic enforcement
Publicize and enforce laws prohibiting alcohol-
