Many experienced motorists develop informal habits that contradict the Highway Code. A common practice is flashing headlights to signal to another driver that they are being let out of a junction, or that it is safe to turn. While often intended as a courtesy, this informal use is highly dangerous and is strongly discouraged.
When a driver flashes their headlights to invite you forward, they may not have noticed secondary hazards, such as an overtaking motorcyclist, an approaching cyclist, or a pedestrian stepping off the pavement. Relying on their signal instead of your own observations can easily lead to a severe collision. Furthermore, Highway Code Rule 111 warns drivers never to assume that flashing headlights is an invitation to proceed. You must always use your own independent judgment and proceed only when you have personally verified that the path is clear.
Misinterpreting flashing headlights can also make you a target for criminal activity. In the United Kingdom, insurance fraudsters exploit informal driving habits through what is known as the "Flash-for-Cash" scam.

Because the official meaning of flashing headlights is merely to signal presence—not to yield priority—the law and insurers will often hold the emerging driver at fault. Practising defensive driving means ignoring friendly-looking headlight flashes and only moving when you are certain it is safe to do so.
During your DVSA theory test preparation, you are highly likely to encounter questions regarding the official meaning of flashing headlights. The exam will test your ability to separate common on-road habits from the legal regulations of the Highway Code.
