you won't get a speeding ticket as long as you don't exceed the limit by more than 10%.

The statement "you won't get a speeding ticket as long as you don't exceed the limit by more than 1" is false. In many places, speeding enforcement can begin at even 1 mph over the speed limit, especially in certain zones like school or work zones where the tolerance is very strict. Generally, there is no official legal allowance that guarantees no ticket if going just 1 mph or a small margin over the speed limit. Enforcement and ticketing depend on local laws, police discretion, and the method used to measure speed, but technically exceeding the speed limit by any amount can result in a ticket.
