When is it permissible to use your high beams?

Using high beams is primarily intended to improve visibility when driving in low-light conditions, such as on highways at night. This is because high beams illuminate the road further ahead and provide better clarity in situations where there are no oncoming vehicles. Highways typically have fewer streetlights compared to urban settings, making high beams particularly beneficial for safely navigating at higher speeds.

It is critical to remember that while high beams enhance visibility for the driver, they can be blinding to other motorists. Therefore, they should be switched off when approaching other vehicles or when driving in areas with sufficient street lighting. This is why other options are not suitable; you cannot use high beams in all conditions or in well-lit areas, as this would create hazards for other drivers. Additionally, high beams are not permitted when other vehicles are present in close proximity, as this can obstruct their vision.
