One theoretical driving test question about fog lights could be: "When should you use your vehicle's fog lights?" The correct answer would be to use fog lights only when visibility is reduced to less than 100 meters due to fog, mist, or heavy rain. It is important to remember to turn off fog lights when visibility improves to avoid dazzling other drivers. Additionally, fog lights should not be used in clear weather conditions as they can be blinding to other road users. **

When all warning lights come on while driving, it could indicate a serious issue with the vehicle. It is important to pull over to a safe location as soon as possible and turn off the engine.

Continuing to drive with all warning lights on could potentially cause further damage to the vehicle. **

If the string still does not work, it may be a sign of a larger electrical issue and it is best to consult a professional. **
