Drivers have been cautioned about the potential violation of Highway Code regulations by using incorrect headlights. Rules 113 to 116 specify the appropriate usage of lights for drivers. Recent complaints from drivers regarding the blinding effect of oncoming headlights have prompted the government to reconsider car and headlamp designs on UK roads.
Motorists have raised concerns about the challenges posed by LED headlights, which are increasingly common in new vehicles, particularly during nighttime driving. While research findings from the Department for Transport (DfT) have not been disclosed, the BBC has reported that the government plans to conduct a new investigation into the root causes and possible remedies.
As outlined in Rule 115 on the official Highway Code website, drivers are advised to utilize dipped headlights, or dim-dip if available, at night within urban areas and in overcast daytime conditions to enhance visibility.
Additionally, drivers are reminded to maintain dipped headlights while overtaking until they are alongside the other vehicle, switching to main beam only if it does not risk dazzling oncoming traffic. The Code emphasizes the importance of reducing speed or stopping if blinded by approaching headlights.
Under Rule 116, the Highway Code instructs drivers to activate hazard warning lights when stationary to indicate temporary traffic obstruction. However, these lights should not be misused for illegal or risky parking situations.
Furthermore, the Code specifies that hazard lights should only be used while stationary on a motorway or unrestricted dual carriageway to warn following drivers of a hazard ahead, ensuring they are deactivated promptly once the warning is acknowledged.
