NIGHT SEAT BELT ENFORCEMENT DEMONSTRATION

AND EVALUATION [Contract - DTNH22-05-R-05094]

Two Study Objectives:

1. Collect information regarding methods of night-time enforcement from law enforcement officers/agencies

and then

2. Demonstrate and evaluate night-time seat belt enforcement program

• Can belt use be improved at night? • Bleed over effect into alcohol?

Slide 5

Slide 6

Page 7: NIGHT SEAT BELT ENFORCEMENT DEMONSTRATION PROGRAM AND EVALUATION

Study Objective 1 - Collect information regarding methods of night-time enforcement from law enforcement officer/agencies

The topical discussion guide was completed March 2006

Contacted Law Enforcement Agency officers who had night belt use enforcement experience

What was discussed? Department characteristics Experience with night traffic enforcement How night enforcement got started Necessary elements for night belt enforcement Inclusion of DWI with night belt enforcement

Slide 7

Page 8: NIGHT SEAT BELT ENFORCEMENT DEMONSTRATION PROGRAM AND EVALUATION

Study Objective 1 - Collect information regarding methods of night-time enforcement from law enforcement officer/agencies

Learned

Techniques of night enforcement varied among LEAs

Checkpoints/Safety Zones Officer Spotters; Two-Officers per Vehicle; Single Officer with Vehicle

Type belt law mattersAmount of manpower and equipment depends on enforcement tacticMore than belt violators out at nightUpfront with media helps with this novel approachExplanation of goals and approach to local mediaLegal counsel needs to be consulted upfrontPolitical support should be soughtIt takes leadership, equipment, and training

Study Objective 2 - Demonstrate and evaluate night-time seat belt enforcement programs in three study communities

Evaluation Questions:

Can night-time enforcement improve the belt use rate at night? At daytime?

Do different enforcement techniques make a difference?

Does a night-time belt enforcement program also deter alcohol impaired driving?

Slide 10

Page 11: NIGHT SEAT BELT ENFORCEMENT DEMONSTRATION PROGRAM AND EVALUATION

Study Objective 2 - Demonstrate and evaluate night-time seat belt enforcement programs in three study communities

Recruitment of Study Sites:

NHTSA Regions were contacted and then States for nominations of potential study sites

Study Requirements:

Population between 50K and 300k

Located in single independent media market

Show support of key parties in community

Have protocol for handling drunk drivers and have SFST officers participating

Have someone on staff knowledgeable of earned media

Conduct traffic enforcement at nightFour 10-day belt enforcement waves; between the hours 10pm and 2am1 wave per calendar quarter in year 2007Second wave synchronized with May CIOT Mobilization

Slide 11

Page 12: NIGHT SEAT BELT ENFORCEMENT DEMONSTRATION PROGRAM AND EVALUATION

Study Objective 2 - Demonstrate and evaluate night-time seat belt enforcement programs in three study communities

In order to qualify for selection, law enforcement agencies had to:

Complete an application

Indicate how they would fulfill the requirements for the study

Identify preferred enforcement tactic

Provide a person to support local earned media effort

Provide official letters of support from community leaders

Provide details for remuneration

SAMPLE NEWS RELEASE

FOR IMMEDIATE RELEASE: [Date]

Charleston Police Department Launches Special Wave of Enforcement at Night

Goal Is to Boost Seat Belt Use—and to Save Lives

[City, State] – In an effort to save more lives on Charleston’s roadways, local law enforcement is continuing to buckle down on those not buckled up—day and night.

According to NHTSA, 69 percent of passenger vehicle occupants killed in nighttime motor vehicle crashes in West Virginia in 2005 were not wearing their seat belts at the time of the crash. That percentage is considerably higher than the 51 percent of passenger vehicle occupants who were unrestrained and killed during daytime hours in the State.

That’s why the Charleston Police Department announced today that they are launching a special “Click It or Ticket” enforcement mobilization to target those not buckled up, especially at night. Special Safety Enforcement Zones will be set up across the city at night to crack down on traffic violations, including seat belt violations, from July 27–August 5. Anyone who is pulled over for another violation and is caught not wearing a seat belt will be ticketed and fined—no excuses.

“Clearly more drivers at night than during the day are taking the attitude that it will never happen to me. But the risk of a fatal crash actually goes up at night,” [Law Enforcement official] said. “That’s why this July and throughout the year, we’re increasing Safety Enforcement Zones to make sure that all passengers, in all vehicles, are buckled up—day and night.”

[Law enforcement official] said regular seat belt use is the single most effective way to protect people and reduce fatalities in motor vehicle crashes. He said that 77 percent of passenger vehicle occupants in a fatal crash who were buckled up survived the crash.

But too many motorists ignore these facts at night. In 2005, 171 passenger vehicle occupants killed in fatal motor vehicle crashes in West Virginia were not wearing their seat belts at the time of the crash. Of this total, 87 of the unbelted fatalities took place between the hours of 6:00 p.m.–5:59 a.m.

“Seat belts clearly save lives. But unfortunately, too many folks in our area still need a tough reminder, so our special nighttime Safety Enforcement Zones are going to help remind folks to always buckle up,” said [Law enforcement official]. “Wearing your seat belt costs you nothing, but the cost for not wearing it certainly will. So unless you want to risk a ticket, or worse, your life, please remember to buckle up day and night—‘Click It or Ticket.’”

What was Discussed:

Thoughts on usefulness of program

Public/Official reactions to program

Unexpected hurdles

Suggested adjustments to program

Future plans for night belt enforcement

  

Slide 55

Page 56: NIGHT SEAT BELT ENFORCEMENT DEMONSTRATION PROGRAM AND EVALUATION

Test Site Exit Discussion

Summary

Usefulness of programAll felt program improved overall traffic safety and belt use in particularAll believed that night traffic activities also deterred crime in areaTwo study locations fostered relationships with surrounding agencies using

overtime/equipment grants from NHTSA

Public/Official reactions to programVery little kickback from citizensOfficials were made aware beforehand and were ready to handle citizen calls

Unexpected hurdlesLack of SFST trained officers in one location (Asheville); partnering with

neighboring agencies brought less trained officers into operationOfficer burnout occurred in later phases of the program in some casesDifficult to keep news media interested in all waves

Suggested adjustments to programShorten length of enforcement period and do more periods to sustain night

enforcement over more time-periods in the year

  

Slide 56

Page 57: NIGHT SEAT BELT ENFORCEMENT DEMONSTRATION PROGRAM AND EVALUATION

Test Site Exit Discussion

Discussion Summary Continued

Test Sites future plans for night belt enforcementContinue to do night belt programUse night traffic operations as a crime deterrent as needed (Greenville)Continue to use incentive equipment for night traffic operations as well as other

needs

Demonstration Project Summary

Evaluation Questions:

Can night-time enforcement improve the belt use rate at night? At daytime?Night belt use improvedIncreases at night typically greater than dayBelt use improved in both high and low belt use locations

Do different enforcement techniques make a difference?

Belt use improved more in checkpoint locations

Checkpoint apparently worked better to garner media interest

Does a night-time belt enforcement program also deter alcohol impaired driving?Positive BACs decreased in Asheville, NCSingle vehicle crashes at night decreased
