Is driving backward while turning creates a smaller turning radius than driving forward?

Question

and please tell me how to compute the turning radius when you consider the size of the car.

im wondering how much space (allowance) horizontally and vertically ill give before i should exactly start to turn at those 90 degree turns. and whats the minimum space should i leave so any part of my car wont hit anything on that 90 degree corner (ex. a wall)

my few geometry and trigonometry knowledge says that the length of my car (from the front wheel to the base(trunk) should be tangent to the turn i should made... ??? ridiculous :)

Answer 1

Go to a parking lot at night
Turn the wheels to the extreme,(R or L),and put it in gear.
Drive in that "Circle" a time or two.
Apply the brakes.put the car in reverse.
give it some gas.
The "Circle" stays the same,only the "Direction" changes.
(Clockwise vs Counterclockwise)

Answer 2

You sure know how to complicate and question that any 16 year old learning driver figures out within a few minutes! As to how much space vertically that you need is the easiest part of the question and never changes unless you change the vehicle you are driving -- it is simply the height of the vehicle, every single time. And Horizontally, it depends if you have an reticulated vehicle or not, but generally you need to be slightly past the halfway mark of the length of the vehicle to get it to turn a corner without any part of the vehicle hitting anything on the inside turning edge of the vehicle.
If you feel the need to measure each time you make a turn, you will soon find yourself going nowhere and having many other drivers who follow you getting very upset with the time it would take you to maneuver around a corner...
The direction the vehicle is going would make no difference in the space needed to turn the vehicle because the length of the vehicle has not changed...
BUT the placement of the wheels on the vehicle can change the space needed to turn, if the wheels are out front of the drivers seat, it takes more turning radius than if the front wheels are place almost directly beneath the driver and the front end is shorter, for example a VW bus or some of the older (early 90's) toyota vans had a very short turning radius as compared to a sedan.

Answer 3

just for sh*ts and giggles..
take your car into a parking lot..
line the car with a parking line..
turn the wheel to the left as hard as you can, and get a friend to measure how far out you go before you circle back to the line, if you do end up back at the line. it depends on your speed. the slower you go the better turning radius you have, the faster you go, the car pushes out farther and the tires hug the road less and you might end up a few feet to the right of the line you started from if you made the 'circle' going left.

the measurement you might need to know for length of the car is not the length of the car, but the length from the bottom of the front wheels to the bottom of the back wheels

get what i'm saying?

you can't have an exact answer to your question unless you wanted a certain speed.

Edit: It also depends on if you weigh (not limited to) 150 pounds.. or (not limited to) 300 pounds.. kay?

Answer 4

Nope

Answer 5

The path of turning while going forward or backward is the same.

Answer 6

Depends on the car.
