Diazepam impairs lateral position control in highway driving
Science (New York, N.Y.)
|July 2, 1982
Summary
Diazepam impairs driving performance, increasing lane variability at higher doses. Even moderate doses may pose risks, suggesting caution with this medication for drivers.
Area of Science:
- Pharmacology
- Human Factors
- Traffic Safety
Background:
- Driving is a complex psychomotor task.
- Medications can significantly affect driving ability.
- Benzodiazepines, like diazepam, are commonly prescribed.
Purpose of the Study:
- To investigate the effects of diazepam on driving performance.
- To assess dose-dependent impairment in expert drivers.
Main Methods:
- Nine expert drivers participated in nighttime highway driving tests.
- Vehicle instrumentation recorded driving parameters.
- Drivers were administered diazepam (5 and 10 mg), placebo, or no treatment.
Main Results:
- 10 mg diazepam significantly increased lateral position variability.
- Some drivers showed potentially dangerous impairment.
- No significant impairment was noted at 5 mg compared to placebo.
Conclusions:
- Diazepam, particularly at 10 mg, impairs driving skills.
- Increased lateral variability suggests reduced vehicle control.
- These findings highlight the risks associated with diazepam use while driving.
