The SPL Top Speed Limiter is basically aimed at light commercial vehicles. It is fitted to the engine and can be programmed to limit both revs and top speeds.
Thirdly, a selectable speed limiter is in its final stages of development and should be available early next year.
Launching the new range, managing director John Southall said: 'On the UK roads last year, 3,431 men, women and children were killed – that equals the contents of seven fully-loaded jumbo jets. These accidents cost £17.4 billion, not to mention the human cost or personal damage. A 10% decrease in mean speed would be expected to result in a 30% decrease in fatal and serious injury accidents.'
