What action should a rider take when approaching a blind intersection?

Answer: C — Slow down and look for vehicles before entering

When approaching a blind intersection, slowing down and looking for vehicles before entering is a crucial safety measure. This action allows the rider to assess the situation and make informed decisions based on visibility and potential hazards. At blind intersections, there may be obstructions like trees, buildings, or signs that block the rider's view of oncoming traffic, so reducing speed gives the rider more time to spot any vehicles that may be crossing their path. This cautious approach helps to establish a clear line of sight and provides the rider with the opportunity to react appropriately if another vehicle emerges unexpectedly. It promotes defensive riding by ensuring the rider is prepared for any sudden changes in the environment, which is essential for safety on the road.
