Motor Vehicle Occupant Injury


ACPM Recommendations:

Strengthening Motor Vehicle Occupant Protection Laws

The American College of Preventive Medicine recommends that all states pass standard (primary) enforcement MSBUL and that this legislation be combined with public education campaigns to increase compliance. The College supports the Model Standard Safety Belt Law, developed by the National Committee on Uniform Traffic Laws and Ordinances. Existing state regulations should be standardized to eliminate exemptions for some passengers and vehicles from compliance. Use of lap-shoulder belts should be required for both front and rear seat passengers. Infants and children should be correctly placed in restraints appropriate for their age and size and such restraints should be used in the back seat of the vehicle, as this is the safest position. The incorporation of higher fines, as well as demerit points, may increase compliance with these laws. However, in light of the limits on the effectiveness of these laws, the College supports further technological innovations in automobiles and roads to reduce injuries from motor vehicles, combined with continued health promotion campaigns.

Task Force on Community Preventive Services Recommendations:

Strategies for Increasing Use of Child Safety Seats, Increasing Use of Safety Belts, and Reducing Alcohol-Impaired Driving

Intervention

Recommendation

Intervention Description

Interventions to increase child safety seat use

Child safety seat law

Strongly recommended

Requires infants and young children traveling in motor vehicles to be restrained in federally approved child safety seats appropriate for the child's age and size. State laws vary regarding the children to whom the laws apply (e.g., according to age, height, weight, seating position, or a combination of factors).

Community-wide information and enforcement campaigns

Recommended

Use media support and child safety seat displays in public sites to promote use.

Use special enforcement strategies (e.g., checkpoints, dedicated law enforcement officials, or alternative penalties) to enforce existing child safety seat laws.

Distribution and education programs

Strongly recommended

Provide approved child safety seats to parents through loans, low-cost rentals, or giveaways.

Include educational components of varying intensity.

Incentive and education programs

Recommended

Provide rewards to children and parents for purchasing and correctly using child safety seats.

Include educational components of varying intensity.

Education-only programs

Insufficient Evidence*

Provide information and teach skills to parents, children, or professional groups regarding the use of child safety seats.

Interventions to increase safety belt use

Safety belt law

Strongly recommended

Requires the use of safety belts by motor-vehicle occupants not covered by the state's child safety seat laws. Existing safety belt laws vary in their requirements. Most are age-based and cover occupants (usually front seat occupants) aged ³ 16 years. These laws leave major gaps in coverage for occupants, primarily those aged 4-16 years.

Specific requirements (e.g., age, seating position, fines, exceptions) vary by state.

Primary enforcement law

Strongly recommended (instead of secondary law)

Primary enforcement law allows a police officer to stip a vehicle solely for an observed belt law violation (without having other reasons for stopping the vehicle).

Secondary enforcement law allows a police officer to issue a belt law citation only if the vehicle has been stopped for another violation.

Enhanced enforcement

Strongly recommended

Increased, rather than routine, enforcement at specific locations and times to target violations of safety belt laws.

Media campaigns that publicize the enforcement activity are an important component.

Interventions to reduce alcohol-impaired driving

0.08% blood alcohol concentration (BAC) law

Strongly recommended

Lowers the BAC at which it is ilegal to drive a motor vehicle from 0.10g/dl to 0.08g/dl (0.08%).

Minimum legal drinking age.

Strongly recommended (i.e., maintaining MLDA at 21 years)

Specifies an age below which the purchase or consumption of alcoholic beverages are not permitted.

Lower BAC for young and inexperienced drivers

Recommended

Establishes a separate, lower illegal BAC (usually £ 0.02g/dl) for drivers targeted by the law.

Studies assessed changes in state laws in the US and Australia. US laws apply to all drivers under the MLDA. In other countries, laws apply to either newly licensed drivers or newly licensed drivers under a specified age.

Sobriety checkpoints

Strongly recommended

At random breath testing (RBT) checkpoints, all drivers stopped are given breath tests for BAC. Such checkpoints are not conducted in the US.

At selective breath testing (SBT) checkpoints, police must have reason to suspect the driver has been drinking before using breath tests.

Media campaigns that publicize the enforcement activity are an important intervention component.

* A determination that evidence is insufficient should not be seen as evidence of ineffectiveness. A determination of insufficient evidence assists in identifying a) areas of uncertainty regarding effectiveness of an intervention and b) continuing research needs. In contrast, evidence of ineffectiveness leads to a recommendation that the intervention should not be used.
