What must you do if your front tire goes flat while driving?

Answer: B — Stop off to the right

When your front tire goes flat while driving, the safest course of action is to stop off to the right side of the road. Continuing to drive on a flat tire can not only damage the tire and rim but also compromise your control over the vehicle. Changing lanes without signaling is not necessary as coming to a stop on the side of the road will alert other drivers to your situation. Ignoring the problem is also not advisable as it can lead to further damage or an accident.
