How will I know if my account is getting low?
Drivers are warned when their account balance is low at the time of crossing.
For drivers crossing the bridge, there is a small LED screen near the barrier which will say LOWBAL. The collectors' will advise ferry users when scanning the tag.
These warnings will vary from account to account dependant on the classification and number of tags on it.
For a single car account, the warning starts when the Tag balance is below £7.50 (9 crossings)
