If it's automatic, check the fluid. Low fluid will do that.I had a similar problem, the car was very slow to start moving. The cause was the transmission range switch was loose and out of adjustment. Another way to tell if this is the problem is to turn the ignition switch on and put it in reverse. …

Yes it could. Why not replace it? It's cheap and most people never do until they stall some dark lonely night. It depends on what kind of car and what engine you have. Go ahead and replace the fuel filter although I don't think it will cure the rough idle. If you have a carburetor, it may need c…

Each insurance company has their own policy, therefore you would need to check with that particular company. Was there an accident? What state did the violation occur? Do you have a license for that state?

Answer It depends on the laws in your state or jurisdiction. The state I live in does not allow photo tickets to become part of your official driving record. Answer Why would it matter? If you went thru the red light, you are guilty of a driving offense, right? So of course the insurance comp…

If you are approaching the intersection at speed limit, and the traffic light changes to amber/yellow at 100 feet or less, that's the point of no return. Slamming the brakes will cause you to stop at or near the cross traffic.

Answer New front brake disks (in the US i think they call them Rotors??) most probably. Perhaps, but much less likely, a worn component on the front suspension somewhere. If it is at a complete stop, your vehicle may need a tuneup or you may have a vacuum leak

Because red means stop and yellow means slow down and green means go!

The answer is yes. As long as you have ENTERED the intersection BEFORE the red light, and you CANNOT safely turn left due to traffic, then a left turn on red is completely legal. This is also because all cars are supposed to be cleared of an intersection upon any red light, to keep traffic flow at t…

Yes, it is no different than anyplace else. If the traffic situation is safe to do so then they can stop you anywhere, generally they try and cause as little disruption as possible. If they think the offender is going to speed off and it just so happens they are nicely boxed in at the traffic lights…

to exicute this correctly; first, you have to be on a one way street. Then the street that you are turning onto must also be a one way street. There for all traffic wanting to make a left hand turn on red, can do so because they are not required to cross oncoming traffic.

A green traffic light means you may go, but only if safe to do so. If there is other traffic or pedestrians in the way, you may NOT go until safe, even if you "have the green light." Even if the other traffic or pedestrians are violating the law, you cannot go until it is safe.
