It is possible to receive a speeding ticket for exceeding the speed limit, even if you have just passed a speed limit sign. Speed limit signs indicate the maximum legal speed that you are allowed to travel on a particular road or section of the road. The purpose of these signs is to provide drivers with advance notice of the speed limit and to ensure safety for all road users.
When you pass a speed limit sign, you are expected to adjust your speed accordingly and maintain a speed that does not exceed the posted limit. If you are caught by law enforcement exceeding the speed limit, whether it's immediately after passing a speed limit sign or at any other point on the road, you may be subject to a speeding ticket or other penalties, depending on the specific laws and regulations in your jurisdiction.
It's important to be aware of and adhere to the speed limits at all times to ensure your safety and the safety of others on the road, as well as to avoid potential legal consequences.
