What occurs on pavement in hot weather when tar is bleeding?

When tar bleeds on pavement during hot weather, it creates a condition where the surface becomes very slippery. This phenomenon occurs as the heat causes the tar to soften and ooze out from the pavement, which can result in a slick surface. Such slippery conditions can pose significant risks, especially for vehicles and pedestrians. Drivers may struggle to maintain control, increasing the potential for accidents.

In this context, it’s crucial to recognize that while the bleeding of tar does not improve traction, it can significantly diminish it, making careful driving essential in affected areas. The other options do not accurately describe the impact of bleeding tar on pavement in hot weather.
