The DVSA has issued a stern ‘no excuses’ warning to drivers
Drivers have been given a stark “no excuses” warning regarding a frequent error that could result in them operating their vehicles unlawfully after dark – and potentially putting others at risk.
In a firmly worded statement, authorities cautioned that numerous drivers are depending on daytime running lights – which can create a misleading impression of safety – rather than activating their proper headlights. Significantly, while these forward-facing lights may seem sufficiently bright, they fail to light up the back of the car, leaving drivers practically invisible from the rear when it’s dark.
The Driver and Vehicle Standards Agency (DVSA) has issued an unambiguous message to motorists: “PUT YOUR LIGHTS ON AT NIGHT!”
What the law actually says
According to Rule 113 of the Highway Code, drivers face explicit legal obligations when travelling after nightfall. Motorists must guarantee that sidelights and rear registration plate lights are illuminated between sunset and sunrise, and in most circumstances must also activate headlights during the night.
The regulations define night as the period between half an hour following sunset and half an hour prior to sunrise – a specification many drivers fail to recognise.
Headlights are also compulsory when visibility is severely compromised, such as during heavy rain, fog or snow.
The hidden danger of modern cars
The DVSA warning shines a light on a growing concern with newer vehicles, where automatic lighting systems and bright dashboard displays can give drivers a false sense of security, leading them to believe their lights are fully operational.
In reality, only daytime running lights may be switched on – leaving the rear of the vehicle completely unlit.
This poses a serious hazard for other road users, particularly on unlit roads or motorways, where vehicles approaching from behind may not spot a car until it is too late.
Fog lights and glare risks
The Highway Code also imposes strict guidelines on the use of lights. Drivers must not use lights in a manner that blinds others, including pedestrians, cyclists and horse riders.
Fog lights, in particular, are frequently used incorrectly. These must only be activated when visibility is severely reduced – and switched off as soon as conditions improve.
Motorists caught in stationary traffic are also advised to release their foot from the brake once vehicles behind have come to a halt, to prevent unnecessary glare.
‘No excuses’
The DVSA’s message is unambiguous: drivers cannot depend on technology alone. With lighting regulations firmly backed by law, failing to use proper lights after dark is not merely careless – it could land motorists in serious trouble with the authorities.
