North Carolina: Is it legal to put a train horn on a car?

Allowed with limits

North Carolina has no express train-horn ban, but making unreasonably loud or harsh sounds with a horn is illegal.

North Carolina requires a working horn audible from 200 feet. It is unlawful to use a horn except as a reasonable warning, or to make any unnecessary or unreasonably loud or harsh sound with a horn or other warning device, so sounding a typical train horn on the road likely breaks the law. The same section bans sirens and compression or spark plug whistles on vehicles other than listed emergency and official vehicles. Horns must also meet any rules set by the DMV Commissioner.

Conditions

  • No unnecessary or unreasonably loud or harsh horn sounds
  • No siren or compression or spark plug whistle on non-emergency vehicles
  • Horn must meet DMV Commissioner regulations
