Visibility is one of a number of factors that do not affect your braking distance per se but can inhibit your thinking distance. The longer it takes for you to spot hazards in the road, the more time will have passed before you hit the brake pedal.

The faster an object is moving, the longer the distance it takes to stop. If a vehicle’s speed doubles, it needs about 4X’s the distance to stop. If a vehicle’s speed triples, it needs up to 9X’s the distance to stop. Weight works in the same way that speed does in relation to stopping distances.

A faster speed increases both thinking and braking distance, increasing the total stopping distance. You might be asked to look for patterns in car stopping distances, and how they change with the speed of a car.

Stopping distance is the total distance you travel before you apply the brakes, plus the distance you travel while the brakes slow you down. Thinking distance+ braking distance = overall stopping distance.

Stopping distances at different speeds

Stopping distances are a favourite part of the theory test, but they’re not easy to remember. There are 3.3 feet in a metre – so divide the distance in feet by 3.3 to get the stopping distance in metres. You’ll need a calculator for that, but it shouldn’t be necessary for the theory test.

1 mph = 0.447 04 m/s. 1 Foot per Second: Feet per Second. In SI units 0.3048 meters per second….Please share if you found this tool useful:

In reducing speed variation between vehicles, the minimum speed limits improve the uniformity of traffic flow by bringing slow vehicles close to the mean speed of the traffic stream, thus, decreasing large speed differentials between fast and slow-moving vehicles.

In California, there are four major Speed Laws: Basic, Prima Facie, Maximum, and Minimum.

427 Slow-moving vehicle to pull off roadway — On a two-lane highway where passing is unsafe because of traffic in the opposite direction or other conditions, a slow moving vehicle, behind which five or more vehicles are formed in a line, shall turn off the roadway wherever sufficient area for a safe turn-out exists, in …

Advice online says you should not break the law to make way for police, fire and ambulance vehicles – this includes entering bus lanes or running red lights. Do not try to speed or outrun an emergency vehicle, only allow the emergency vehicle to overtake only when there is space to do so and it is safe.

Answer – It’s true. Ambulance drivers don’t drive as quickly as, say, police during a high-speed chase. Bressler said ambulances travel more slowly through traffic when they have a patient on board for safety reasons, as well as the comfort of the patient.

On a Street: If you hear a siren or see flashing lights on a street, you should: Pull over to the right when safely able to do so; Slow down and stop to make a safe lane of passage for the emergency vehicle.

Failing to move over when being approached by an emergency vehicle is a Class 2 misdemeanor. There is also a hefty fine of $250.00 plus court costs imposed on someone who is convicted for failing to move over for an emergency vehicle. The penalties are more severe if an emergency vehicle or work is hit or injured.

If you are on an interstate or highway, there is usually an adequate amount of space on the right side of the road for you to pull over there. Never pull over on the left side of the road, even if there is a median.

Why should you not turn your wheels while you are waiting to make a left turn or U-turn? a. If you are hit from behind you could be pushed into oncoming traffic. You could confuse oncoming traffic.
