My mum has recently received a letter in the mail for speeding fines which read that she was doing 35km over. 135km in a 100km zone, but she believes she wasn't going that fast. Yes, she may have been slightly speeding but not to this extent. I just want to know if there's anything that can be done to try and fight it? As it carries 5 point demerit points, $855 fine and 3 months loss of drivers licence.
