On 70mph limit motorways, those who drive at less than 83 mph will get the lowest penalty of £40 and two points. Those who drive between 84mph and 93mph will face a £60 penalty and three points. But motorists caught driving at 94mph or more will have to pay £100 and have six points automatically on their licence. At present, exceeding the speed limit by between five and 14mph results in an automatic three point penalty.
