A programmable audible warning system uses audio messages for people and is fitted to vehicles and powered through the vehicles 12v DC supply 1 or a rechargeable battery 4. The system processor 6 uses signals 2 from a series of the vehicles switches or additional switches to define when a particular message will be played. The audio is produced by output 7 and sent to a speaker 8. The switches may include those related to doors, temperature sensor, engine ignition, reversing, trailer connections. The messages may also include safety slogans or review risk assessments. The audio messages can be changed by the end user and audio files may be stored on a removable memory 10.
