What is the most effective way to deal with a 'tailgater'?

Answer: C — Make it easier for the 'tailgater' to pass

Tailgating can be a dangerous practice and the most effective way to deal with it is to make it easier for the tailgater to pass. Speeding up or braking sharply can escalate the situation and put yourself and the tailgater at risk. Ignoring the tailgater may not resolve the issue and can also be dangerous. It is best to stay calm and allow the tailgater to pass safely. Always prioritize your safety on the road.
