If youi are one of those motorists who thinks they're being helpful by flashing their lights to signal the presence of speed cameras, think again. While it may seem like a considerate act, you're actually breaking traffic rules.
You could even end up with a substantial fine. The Highway Code defines acceptable uses of headlights in Rule 110.
That rule says: "Only flash your headlights to let other road users know that you are there. Do not flash your headlights to convey any other message or intimidate other road users."
Moreover, according to section 89 of the Police Act 1997, obstructing a police officer in the execution of their duty, which could include headlight signaling, is an offense, potentially incurring a fine of up to £1,000.
This potential penalty is notably higher than the minimum fine for being caught speeding by a camera, which stands at £100 alongside three points on the driver's licence, as reported by Birmingham Live. It's common for drivers to flash their headlights as a warning about mobile speed cameras, often catching fellow motorists off-guard.
Although many drivers continue to use headlight flashes as informal warnings, prosecutions do happen. In one case from 2011, a motorist was penalised for doing just this in a case that made national headlines.
The driver in the north-east of England ended up in court, and received a fine of £175, after trying to caution others about safety. Additionally, he was ordered to pay £250 in costs and handed a £15 victim surcharge.
When can I flash my lights or beep my horn?
The Highway Code has strict rules about signalling to other drivers. According to Rule 110, there's hardly ever a good time to flash your lights.
Rule 111 goes into more detail, warning: "Never assume that flashing headlights is a signal inviting you to proceed. Use your own judgement and proceed carefully."
And when it comes to the car horn, Rule 112 is specific: "Use only while your vehicle is moving and you need to warn other road users of your presence. Never sound your horn aggressively. You MUST NOT use your horn except when another road user poses a danger."
