High Speed events are recorded when you drive more than 10 miles per hour in excess of the speed limit*. In nearly all cases, this is faster than the flow of traffic. In addition to increasing your crash risk, high speed driving also puts the driver at risk of a speeding ticket.
On an individual trip, you can see how long you were driving at high speed (each minute of high speed driving counts as one ding). High Speed also factors into your total score, where your High Speed rating indicates how often you trigger High Speed events, with less events resulting in a higher score.
*Note that while we source our speed limit data from the best sources available, the data may not always be up-to-date. The impact of High Speed time on your total score has been adjusted to take this into account.
