Have you ever swerved into another lane to avoid an object in the road? Have your forgotten to put on your turn signal when changing lanes? Any of these actions constitute an unsafe lane change under most state laws. Other examples of an unsafe lane change violation include: Changing lanes and breaking hard. Making an abrupt lane change. Weaving in and out of traffic. If you are ticketed for making an unsafe lane change, you will face fines. If you live in a state with a points system, you will see some added to your driver's license. In Texas, any moving violation will add two points to your license and your driver's license can be suspended if you have six points added in three years. In California, a moving violation will only add one point but if you get four points on your license in a 12 month period, your license can be suspended or revoked.
