Um...don't wreck.
This makes your parents very unhappy and the insurance people will love the big $$$$$$ you'll have to start paying them.
See/hear an emergency vehicle approach, slow down and/or stop pulling to the right if possible to do safely. Don't stop in a sharp curve or on the crest of a hill as that creates a very dangerous situation (you wouldn't believe the number of people who do this...sad part is most are driving expensive cars which makes you wonder
).
If you live in an area prone to snow, go and practice in a large empty parking lot before driving on the roads. This'll let you see and feel the difference.
If you have access to a sportier car (doesn't have to be a Mustang or Camaro...my first time was in a 91 Volvo 740 Turbo, and I placed in the top 1/3), think about participating in a SCCA Solo event in your area. These are closed course timed events (usually in large parking lots) where you race around a cone course. It helps to get that "hot rod" itch out of you blood safely, and you learn ALOT about how your car handles...plus it's a helluva lot of fun too.

Even though you might drive good, never trust anyone else to. I've actually been cut off by a nun before on I-75 (who would have guessed !?! She was even in a car that had the church name and stuff on it).
If you want a cheap car that'll last forever (if properly maintained), is cheap to insure, and safe...buy a Volvo. Some are even fairly quick. I'd suggest 1990 to 1991 740 models, with the turbo (stay away from 16v GLE models, and the nonturbo is ok but slow). Even pretty cheap to repair, kinda in between a Ford and Toyota cost wise.
