Totting up is the system where a driver who builds up 12 or more penalty points within three years faces disqualification. The points accumulate from separate offences and are counted from the dates of the offences, not the convictions.
In one line: Totting up disqualifies a driver who reaches 12 or more penalty points within a three-year period.
How totting up works
Totting up operates under the Road Traffic Offenders Act 1988. When a driver reaches 12 points across three years, the court must impose a disqualification, normally for at least six months, unless an argument against it succeeds.
For example, a driver with 9 points from earlier speeding offences who picks up another 3-point speeding penalty reaches 12 and faces a totting-up ban. The exact period depends on any previous disqualifications within the past three years.
New drivers face a stricter rule: 6 points within two years of passing revokes the licence entirely, sending them back to learner status.
Totting up vs exceptional hardship
Totting up is the rule that triggers a ban at 12 points. Exceptional hardship is the argument a driver can raise to ask the court to avoid or shorten that ban despite reaching the threshold.
Unlike a discretionary ban for a single serious offence, a totting-up ban is driven purely by the running total of points, so each minor endorsement edges a driver closer to disqualification.
