Vaikom: Many drivers often encounter frustration due to the glare from oncoming headlights during night driving. The failure to dim headlights on these vehicles is a frequent cause of accidents. According to the Motor Vehicle Driving Regulations of 2017 (Section 31(4)), drivers are required to dip their high beams in a timely manner when driving close behind another vehicle or approaching an oncoming one.

Under Section 117 A of the Motor Vehicle Act, officials from the Motor Vehicles Department can file a case; however, only the court holds the authority to impose fines. The penalty for the first offence is Rs 500, and for a second offence, the fine rises to Rs 1,000.

A vehicle's high beam is designed to project light in a straight line over a longer distance, typically exceeding 100 metres. Conversely, when headlights are in dim mode, the light is reduced, ensuring less glare for oncoming traffic.

Many automakers have started replacing traditional halogen headlights with modern technologies such as light-emitting diode (LED), high-intensity discharge (HID), and projector lamps. These parts are manufactured with approval from the Automotive Research Association of India (ARAI) under Central Government regulations. ARAI ensures that the intensity of headlights remains within permissible limits before granting approval for vehicles to be released on the road.

Authorities have clarified that the Motor Vehicles Department lacks the authority to take action against company-installed headlights, as these are ARAI-approved.

When should headlights be dimmed?

Drivers are required to dim their headlights in the following situations:

  • When an oncoming vehicle is within 200 metres
  • On roads with functional streetlights
  • When driving closely behind another vehicle
  • When signalling a turn at night
