The process of directing a vehicle’s forward illumination devices involves precise adjustment to ensure optimal visibility without causing glare to oncoming traffic. Proper alignment is critical for safe nighttime driving. Misalignment can severely limit a driver’s field of view and increase the risk of accidents.
Accurate projection of light enhances driver reaction time and reduces eye strain during nocturnal operation. Historically, these adjustments were performed primarily by mechanics using specialized equipment. Regulations often mandate specific aiming parameters to comply with safety standards and minimize discomfort for other drivers on the road. Correctly adjusted devices contribute significantly to overall road safety.
