When changing lanes on a highway, you should:

Increase your speed to pass the vehicle quickly
Signal, check your mirrors and perform your move safely
Change lanes without signaling
Pass vehicles on the right side

The correct answer is: Signal, check your mirrors and perform your move safely

When changing lanes on a highway, it is important to signal, check your mirrors, and perform the move safely. This ensures that other drivers are aware of your intentions and reduces the risk of accidents. Option A is incorrect because increasing your speed can be dangerous and it is important to maintain a safe speed when changing lanes. Option C is incorrect because it is illegal and dangerous to change lanes without signaling. Option D is incorrect because it is only legal to pass vehicles on the left side, not the right side.
