Within built-up areas, is it permitted to use dipped or main beam lights alternately at very short intervals?
Lighting
Explanation
Within a built-up area, it is possible to use **dipped or main beam headlights** intermittently to **avoid a potential accident**. This is done by quickly turning the lights on and off to **warn other drivers of a danger** without dazzling them.
- **Main beam headlights** are generally prohibited in towns and cities, but their intermittent use is allowed to alert about a danger.
- This intermittent use is an exception to the general rule of not using main beam headlights in urban areas, as safety and accident prevention are priorities.
Therefore, in situations where there is a risk of an accident, dipped and main beam headlights can be alternated to warn other drivers.
