Just a day after a CTV News investigation revealed that many motorcyclists are being overcharged because of a tolling glitch on the Golden Ears Bridge, TransLink says drivers will be automatically refunded for the errors.

CTV's Chris Olsen found that some drivers were being overcharged up to $2 more per crossing because the laser detection system is registering the bikes as four-wheeled vehicles.

John Waddington has had it happen to him nine times in 12 crossings since April.

"At least four of them [my friends] have got the same problem with invoicing for cars instead of motorcycles," Waddington said.

He was reimbursed after lodging a complaint.

Today, TransLink promised to go over Waddington's account back to his initial registration date.

"I have had word they are going to back of the beginning of my history with them, my registration, and audit my crossings and send me a credit for any overcharges. And there will be lots," Waddington said.

TransLink spokesman Ken Hardie, who says the system is supposed to be accurate 97 per cent of the time, told CTV News other drivers will be given an automatic refund.

"It would definitely be a situation where we go back and we discover that this problem exists on a certain account then that account would be credited," Hardie said.

But should you rely on the same system that overcharged you to find the error and correct it by giving you a refund?

Even TransLink's spokesperson says he'd check his bills.

"If it was me I'd want to check the bill, personally, just to find out if there were any anomalies in there and if there are then obviously I would check with the office to make sure they were dealt with," Hardie said.

And Waddington's advice is to check your bills and ask for an audit back to the beginning.

"Their computer system will only allow back six months, but definitely go back to the original date of registration," he said.
