When someone is speeding, they're driving their car too fast for the road conditions.
Speeding is a common problem on roads everywhere. You might have seen cars zooming by with their drivers breaking the speed limit. Usually, this happens because people are in a hurry to get somewhere or don't realize how fast they're going. Sometimes, speeding can be more serious than just a minor mistake - it's an action that puts not only the driver but also other road users at risk of getting hurt.
