Final answer:
Very slow driving is especially dangerous just after rounding a curve.
Step-by-step explanation:
Very slow driving is especially dangerous in situation B, just after rounding a curve.
When driving around a curve, it's important to maintain an appropriate speed that allows for proper control and maneuverability. If a driver is going very slow just after rounding a curve, it can increase the risk of a collision because other drivers may not anticipate the sudden decrease in speed. This can lead to rear-end collisions or other dangerous situations.
For example, if a driver is coming around a curve and suddenly slows down, the driver behind them may not have enough time to react and could potentially collide with the slower vehicle. Additionally, if a driver is going slow around a curve, they may not have enough momentum to navigate the curve effectively, increasing the risk of losing control.
