Which of the following is not a safe driving practice when driving on the interstate?

You should always signal when moving your vehicle to the right or left. On an interstate, you should stay in the right lane if you are moving more slowly than the surrounding traffic. It is illegal to back up or make a U-turn on interstate highways, so if you miss your exit, you should proceed to the next exit.

• Slower traffic must keep to the right.
• Change lanes without signaling.
• If you miss your exit, you must go to the next exit.
