Answer:
The correct answer is A: Maintain a safe speed and keep to the right
Step-by-step explanation:
When approaching a curve with poor visibility, the safest course of action is to maintain a safe speed and stay to the right side of your lane.
The reasons for this are:
- Maintaining a safe speed gives you time to react if there is any hazard in the curve you cannot see yet due to the poor visibility. Going too fast limits your reaction time.
- Staying to the right side of your lane positions you best in case there is an oncoming vehicle in the other lane that you cannot see yet. Being as far to the right as safely possible gives the other vehicle more room if needed.
- Driving in the middle of the road (Option B) is not safe because you have less time to react if there is a hazard on either side of the road and you reduce the space for any oncoming vehicles.
- Staying to the left (Option C) is equally unsafe as it does not position you well for dealing with potential oncoming traffic or hazards on that side of the road.
So in summary, the safest approach when encountering a curve with poor visibility is to reduce your speed to a level that allows you to react in time and position your vehicle as far to the right as is safely possible within your lane. The other options are riskier and reduce your response time or space to maneuver.
