Acceleration while going around a curve can actually be a big no-no. It’s worse in a RWD than FWD car, but it’s just not a good idea. LordVor explained this well: resource allocation. It takes a certain amount of force (acceleration) to make your tires break traction with the road. When you turn, you are accelerating even if you have your foot off the gas. This puts force on the tires. Giving the car puts MORE force on the tires. The more force you have on the tires, the more likely they are to lose grip. In slippery weather, don’t apply gas until you’ve straightened out of the turn.
General advice is to slow down and leave plenty of room between yourself and other vehicles on the road. This is probably the most important thing you can do. This is true even if you have AWD. AWD helps you maintain grip while moving. It does NOT make you slow down any faster.
Also, if you are driving in snow and in winter, at some point you are going to slide. The basic, catch-all advice for this situation is to steer into the skid. There are some little specifics that differ between FWD and RWD drive cars, however. In a RWD car, it is the rear wheels that will slide. What this means is that when you skid, you rear end of your car is going to swing out to either the left or right. Get off the gas and steer into the skid. Chances are good that you’ll then have to steer back the other direction as the back end skids to that side. Just keep steering into the skid.
FWD cars are a little different because you can do a couple of different things depending upon your speed. At low speeds (as in, going up a driveway speeds, not 30mph) the front end may slide to the left or right as you apply power and the wheels spin. Dealing with this is simple: just turn the wheel in the direction you want to go. This could mean you turning the steering wheel like crazy and looking like a fool as the front of your car slides left and right, but hey, you made it up your driveway, right?
At any kind of real speed on a real road, this is NOT a good idea. The way a RWD drive car skids is that (around, say, a turn) the front tires keep traction while the rear wheels slide, and so the rear end of the car slides toward the outside of the car. In a FWD car, the front wheels will lose traction and slide. What this means is that the front wheels are turned, but the car is continuing to move in a straight line. This, you might understand, is a Bad Thing. At this stage, you have a couple of options:
1: Just brake. If you’re going slow enough, this might be the best idea, and unlike in a RWD skid, you still have some braking power available at the rear wheels. But you have to be going slow for this to work.
2: Steer into the skid. It’s simple, but a little different from steering into a RWD skid. Instead of turning the wheels completely in the opposite direction, you just want to get them facing in the direction you are moving, which is usually straight forward. Once you get them straight, you again have a couple of options:
a: Brake. You can brake much more effectively with four wheels than with two!
b: Attempt to steer back onto the course you want to follow. This could result in you sliding all over again.
Use your judgement, obviously. And to be fair, it’s going to be hard to go through all of this. The most that most of us would be able to do would be to think “Sliding!? BRAKE!” - which in a FWD drive car, isn’t the worst thing you could do, but which is useless in a RWD car. So practice. But the best thing to do is to go slow, which minimizes the consequences of an unexpected skid, i.e. you slide onto the shoulder and come to a quick stop, versus you careen off the road, through the guard rail and down the ravine into the river.
Also, one more thing about AWD and 4WD: while these systems are great for maintaining traction and staying on the road (AWD more than 4WD) they aren’t immune from skidding. In fact, it can be especially dangerous to slide in an AWD car because, unlike a FWD or RWD car, you cannot predict in which manner the car is likely to skid - it can go either way, or neither (and a slide in which all four wheels are out of traction with the road is not something I would wish on my worst enemy). So drive slow, keep your distance, and be careful!
Sorry for the long post y’all.
