When you change lanes, you keep awareness at every moment of the move because traffic can change in an instant. Checking your mirrors and blind spots before you signal and start the lane change ensures there’s a safe gap and you won’t merge into a vehicle. As you steer into the new lane, you continue scanning to catch any vehicle that might be closing in or attempting to slip into the space you’re about to occupy. After you’ve finished the lane change, re-check to confirm you’re fully clear in the new lane and there’s no one in your blind spot or closing in from behind. This continuous verification helps prevent surprises and keeps your maneuver smooth and safe. Options that limit checks to only one time miss the safety needed before, during, or after the move.

Hydroplaning happens when a thin layer of water builds between the tires and the road, reducing grip. The safest response is to ease off the accelerator gradually, avoid braking hard, and steer smoothly in the direction you want to go. This lets the tires reconnect with the road as the water is squeezed away, helping you regain traction and maintain control. Braking hard can cause the wheels to lock or skid, accelerating can worsen the loss of traction, and abrupt steering can lead to a loss of directional control since the tires aren’t gripping the surface. By staying smooth—slowing gradually and steering steadily—you regain traction and can continue driving safely.

Entering a perpendicular parking space safely means lining up and guiding the vehicle straight into the space. You approach with enough distance from other parked cars, bring the front bumper in line with the opening of the space, and then steer to center the vehicle inside. This keeps you clear of adjacent vehicles and the curb, makes it easy to exit later, and helps you judge the space width as you go in. Other approaches that start at an angle without regard to distance can lead to misalignment or contact with nearby cars or curbs, so the straight, centered entry is the correct method.

Passing in curves or near intersections is unsafe because your view of oncoming traffic and other hazards is limited in those areas. You need a long, clear sightline to complete a pass safely and return to your lane before meeting traffic coming from the opposite direction. The rule you should follow is to pass only where the road markings show a broken line and you can be sure the opposite lane is clear for the distance needed to pass. Near curves or intersections, that visibility isn’t guaranteed, so passing is not allowed. Other options aren’t safe or are outside the rule: passing when the road appears straight and traffic is light might seem fine, but it ignores the surrounding visibility constraints of a curve or intersection. Trying to pass because the vehicle ahead is slow near an intersection is dangerous, since you could misjudge the gap or hidden traffic. and passing only at pedestrian crossings would put pedestrians at risk and isn’t a proper or safe passing rule.
