Motorists could face fines of up to £70 for improper use of their car horn, under Rule 112 of the Highway Code. The rule states that horns should only be used while the vehicle is moving and to warn other road users of your presence. Using the horn while stationary, such as when stuck in traffic or to signal arrival, is prohibited.
The rule also applies in private driveways and restricts horn use in built-up areas between 11.30pm and 7am. However, an exception allows horn use when another road user poses a danger, even if stationary or during restricted hours.
Penalty Charge Notices (PCNs) for horn misuse typically cost £50-£70, reduced if paid within two weeks. Ignoring a PCN can lead to court action and fines of several thousand pounds.
Drivers are also reminded that horns must be operational for MOT tests. The horn must be loud enough to be heard by other road users, and its sound must be continuous and uniform. Gongs, bells, sirens, and novelty horns are forbidden, except for classic cars manufactured before 1906.
