When you feel drowsy while driving, the safest move is to stop at a safe place, rest, and resume driving only when you’re alert again. Drowsiness slows your reaction time, narrows your attention, and can cause you to drift or briefly fall asleep, which dramatically increases the risk of a crash. Continuing to drive won’t fix the sleepiness and keeps you at higher risk even if you think you can push through. Turning up the radio doesn’t restore alertness, and while you might gain a moment of focus with extra distance, that alone can’t counteract the reduced perception and delayed responses caused by fatigue. Instead, find a secure spot to pull over, take a short nap (about 15–20 minutes) or rest until you’re refreshed, and only continue once you’re alert. If possible, switch drivers or arrange for a longer rest period to ensure safety.

Never stop directly over a pedestrian crossing or bicycle crossing. Pedestrians and cyclists have the right of way on these crossings, and a vehicle blocking them is unsafe and typically illegal. If traffic is congested and you would have to stop on top of the crossing, you should stop before the crossing and wait for space to clear, or only move forward if you can completely clear the crossing without blocking it. This is why the statement is false.

On-ramp merging relies on matching the speed of highway traffic before you blend in. Use the acceleration lane to bring your speed up to the flow, then look for a safe gap and merge smoothly into traffic. This keeps the traffic moving and gives drivers behind you time to react. Entering before you accelerate creates a speed difference with the surrounding vehicles, making it hard for others to anticipate your move. Stopping at the end of the ramp blocks the ramp and wastes a potential gap you could have used. Merging by changing lanes immediately without signaling hides your intentions and can surprise drivers, raising the risk of a collision. Signaling, checking mirrors and blind spots, and merging when you have a safe opening is the proper approach.

Flashing yellow signals mean proceed with caution, not stop. Slow down, look for pedestrians and other vehicles, and continue through the intersection only when it’s safe, yielding to anyone who has the right of way. You don’t come to a full halt unless there’s a specific reason to stop (like a vehicle or pedestrian in your path), which is why the statement is false.
