A wave or thumbs-up might seem like a harmless way to thank another driver, but it could result in a £1,000 fine, three penalty points, or even a discretionary driving disqualification. According to Brett Tinkley from Lexham Insurance, such gestures breach rule 160 of the Highway Code, which requires drivers and riders to keep both hands on the wheel or handlebars to maintain full control.
Under the Road Vehicles (Construction and Use) Regulations 1986, removing a hand from the steering mechanism is considered a loss of control. This rule applies to all vehicle types, including cars, motorbikes, mopeds, and scooters. The only exception is when indicators fail, in which case hand signals may be used. Motorbike riders also commonly use hand signals to communicate, but these actions are not without risk.
Brett Tinkley, motoring expert at Lexham Insurance, said: “We’re a polite nation, so motorists might instinctively wave a hand to express gratitude to others especially if new to the roads. But doing so is a temporary distraction that ultimately reduces your control over the vehicle and could delay your reaction to other road activity. This is particularly important when travelling at speed, navigating complex road layouts or in heavy traffic. If you’re on a motorbike, moped or scooter, balance can be affected more so in windy or wet conditions. A hand movement might also draw the attention of another motorist for a second too long. These factors could compromise the safety of you and those around you, despite very best intentions. Therefore, it’s wise to keep both hands on the steering wheel or handlebars where possible. Nodding your head and or smiling in acknowledgement is often a visible sign to another driver or rider, especially where it’s harder to see electronic signals on a two-wheel vehicle. That way, your gratitude is as safe as it is courteous.”
Other common ways of expressing thanks can also lead to penalties. Using hazard lights to signal appreciation is not permitted while driving under rule 116 of the Highway Code, except on motorways or unrestricted dual carriageways to warn of a hazard ahead. This practice is also restricted by the Road Vehicles Lighting Regulations 1989. Although there is no fixed penalty for improper use, it may contribute to other driving offences.
Flashing headlights to thank another road user is also discouraged. Rule 110 states headlights should only be flashed to alert others of your presence. Using them to say thank you or to warn of police ahead is a criminal offence under the Police Act 1996 and could result in a fine of up to £1,000 or even one month in prison.
Tinkley added, “Miscommunication might happen when lights are used incorrectly. For example, flashing headlights could be deemed an invitation to come forward. With hazard lights, the vehicle behind might slow down unnecessarily assuming you’re in trouble. This can be problematic in rainy weather particularly when a vehicle’s stopping distance increases. UK habits aren’t universal, either. If you plan on driving or biking abroad this summer, be mindful that flashing could contrastingly be considered rude or aggressive in other cultures. Motorists might do so to force others to speed up or move over. Should your well-meaning action be misinterpreted, there’s a risk of someone else retaliating in anger. It’s wise to research the road laws and customs of the country you’re visiting beforehand. If in doubt, avoid using hand or vehicle signals. Ultimately, finding or reminding yourself of the rules keeps roads, at home and away, safe.”
