I was driving a friend's car and I didn't have a pass or a CityLink account

If you're driving a friend's car, you can still buy a pass or open an account for your trips – you don't need to be the vehicle owner.

You can buy a pass or open an account after you've travelled, but there are time limits for doing so. 

For 24 Hour Passes, you have until midnight on the third day after you travelled.

For Weekend Passes, you have until midnight on the Tuesday after the weekend on which you travelled.

For accounts, you have until midnight on the seventh day after you travelled to open an account or add a vehicle to an existing account.

If you don't cover your travel within these time frames, a toll invoice will be sent to the vehicle's owner. If you aren't the registered owner of the vehicle, you can still pay the toll invoice. All you need to do is visit the pay toll invoice page, enter the toll invoice number and proceed through the payment process.
