Caroline Cooney's Drivers Ed is about several high school students experiencing all the ups and downs of learning to drive. As teenagers they are very mischievous and just enjoy a good time, but when a mother is found dead as a result of something they are guilty of, it seems like there lives will change forever.
Remy, Lark, and Morgan are mischievous friends who plan to go out to steal certain signs one night. None of them have their licenses, so Nicky Buddy drives. He is one year older than all of them, and he lives by Morgan so he is a friend with him. Remy decides that she want a Morgan Road sign, they get a "Thickly Settled" sign for Lark, and Morgan takes a Stop sign. Also, Remy and Morgan kiss when they are in the car. When Remy comes home, Mac starts to question her and she has to hide the Morgan Road sign in the bushes to make sure that Mac doesn't tell their mom what she did.
That night, Morgan is watching the news and he sees a thing on about how a stop sign was taken off of Cherry Road and some mother was hit by a truck and died. Morgan then realizes that it was the sign that they took. Morgan's dad then says, "Whoever took that sign should be shot."
It was Friday, so she didn't have to worry about school, but all she could think about was the sign. What if her class found out? Saturday passed, and still, she couldn't think of anything but the sign. Then Morgan's family decides to start going to church, and this makes Remy think that Morgan told. But then she realizes they only went because his dad is running for governor. After church, everyone went to the basement to have cake and coffee, but Morgan couldn't eat because every time he put cake in his mouth, he thought of the lady never eating again. Then Mac walks over to Morgan and starts telling him about how Remy likes him so much, and how their mom has pre-qualified him for marriage. He pretty much embarrasses Remy. The next Monday morning, Remy's mom is taking her and Mac to school when they notice that 43 mailboxes are destroyed. Her mom said they should be shot, and this made Remy think what she would think of her if she found out that it was she that took the sign. That day in school, a cop comes and talks to the class about the accident. Remy and Morgan are scared, but all the cop says is don't do it. Nothing happened on Tuesday or Wednesday, but on Thursday, a full-page ad was in the paper, paid for by the lady's husband that said: Who murdered my wife? I don't know, but I'll find out. Look at this beautiful woman. Only twenty-six. You killed her. You ended her life, and left mine empty. Don't sleep tonight! Murderer!
In the next section of the book, Morgan decides that he can't take it anymore and tells Nickie that he has to tell about it. Nickie just said, "Don't do it yet, let's talk." Morgan calls for Remy, but she's not there so he tells Mac to have her call him and say that he is going to tell. Remy then goes to call Morgan, but Mac interrupts her and says, "Tell what? What is he going to tell?"
"Gossip," Remy says.
Then Morgan goes to Nickie's house, and they talk about what would happen if they tell. To prevent Morgan from telling on them, Nickie says that if he tells he is going to say that Remy and Morgan wanted to see an accident and that they were glad that a woman died. This stopped Morgan from telling. Back at Morgan's house, there are a bunch of lawyers watching the news. The ad comes on, and Morgan asks them what would happen to the kid if they found him. They said that being it would probably be his first offense, he would be fined $50 and have to do some community service. The reason for that is that all they did was take the sign, they didn't kill anyone. Morgan tells Remy about Nickie's threat and that scared her. She's afraid that her parents might actually believe him. Then the days begin to pass very quickly and nothing is heard about the accident for a while. The ads stop, and most everyone forget about it.
In the last section of the book, Remy takes her driving test and passed it, but on the way out, she tells Mr. Fielding that it was her who took the sign and that she is going to tell her parents tonight. She takes her car out and goes and picks up Morgan. She tells him that she told. Morgan decides that he better tell his parents also. He tells his dad and his father just sits there in disbelief. Then it tells how Remy told her parents and how they went nuts. Her mom thought she was a bad mother, and her dad just couldn't believe it. Remy's father doesn't know whether to bring in the police or not. Then he called Nickie's parents, but they convince him that he wasn't involved. A meeting between Mr. Fielding, Remy's family, and Morgan's family is arranged. At the meeting, Mr. Fielding says that he thinks Morgan and Remy should be punished. They don't agree on whether to call the cops or not. The next day, they decide to go and talk to Mr. Thompson. They apologize for what they did and Mr. Thompson realizes that if they're sorry, that's good enough for him. Then the next day, Mr. Fielding takes Remy and Morgan to look at the grave of Denise Thompson. They say they're sorry again.
