Motorists caught speeding could end up forking out up to £2,500 in fines when changes to the law come into force next month.
The maximum possible fine for driving above the speed limit, £1,000, is due to be hiked by 150% from April 24th.
This means from that date, depending on how serious the offence is, offenders could be charged up to 175 per cent of their weekly income.
Drivers caught at speeds up to 10 mph over the limit are classed as band A, with band B fares relating to offences where motorists were clocked at 11-21 mph over the limit. Class C is the most serious category which applies to drivers exceeding the speed limit by more than 21 mph.
Offenders in Band C face fines between 125 and 175 per cent of their weekly wage, which will be limited to £2,500.
First time speeders can avoid the increased fines if they take a speed awareness course, although this option does not apply to repeat offenders.
