In parking, the aim is to complete the maneuver with a single, controlled backing into the space. Backing more than once shows you didn’t execute one smooth, planned move and instead make adjustments after starting the maneuver. The statement that describes this behavior—backs twice, meaning two parking attempts—directly captures the idea of performing multiple backs rather than a single, decisive entry. The other descriptions describe separate issues you could encounter while parking (hitting something, backing at high speed, or not releasing the parking brake). They don’t convey the act of performing more than one back during the parking attempt, which is why they’re not the best match.

Stopping in a way that blocks a marked crosswalk is bad because it directly prevents pedestrians from using the crosswalk safely and legally. Crosswalks are where pedestrians have the right of way, and you’re expected to stop before the crosswalk or at the stop line, not on or over it. When your vehicle sits in the crosswalk, pedestrians may be forced to step into traffic or wait in a dangerous position, increasing the risk of a collision. So the key message is: keep the crosswalk clear whenever you’re stopping. The other actions described may raise safety or legality concerns for different reasons, but they don’t specifically involve blocking the crosswalk itself. Bumping the curb sharply could indicate loss of control or damage. Entering the intersection on amber is allowed if you can do so safely. Interfering with other vehicles’ right-of-way is dangerous, but it isn’t about occupying or blocking the crosswalk.

Failing to yield the right-of-way, and thereby forcing other drivers to stop, is an illegal and unsafe driving behavior. When you don’t yield when you should, you interrupt the flow of traffic and compel others to stop or brake abruptly, increasing the risk of a collision and creating unpredictable traffic conditions. This exactly describes the act in question: forcing others to stop by not yielding. The other described actions are proper driving practices. Yielding to oncoming traffic when appropriate is correct and safe. Stopping at a clearly marked stop sign is obeying signals and rules. Maintaining a safe following distance helps prevent rear-end crashes. None of these involve forcing other vehicles to halt by failing to yield.

Safe driving around signals means obeying red lights and stopping when a stop is required, then proceeding only when it’s safe. The bad behavior shown here is not stopping when it’s necessary. Ignoring a required stop undermines the signal that’s meant to prevent collisions with cross traffic and pedestrians, so it puts everyone at risk. In contrast, reading the intersection ahead and proceeding with caution reflects prudent awareness and caution; stopping promptly at a red light is correct and required; and while trying to rush a yellow light is a risky instinct, it isn’t about purposeful ignoring of a necessary stop. The key idea is that not stopping when you must is unsafe and improper control of the vehicle in response to signals.
