The best way to learn a language while driving is to start listening to the language and practicing. There are many ways to do this, and people even say that it is possible to learn a language subliminally while sleeping. If that is the case, then the same rules could apply while a person is driving.
When listening to your english speaking course, there are language learning CDs and other recordings, or you can listen to a radio station in another language while driving. I suggest also watching movies or television shows in another language that you’re trying to learn. This helps you to think in the language, instead of just using memorization techniques.
Nowadays, there are apps for leaning languages that you can use while you’re driving. Of course you’re not going to be touching your phone, but you sure can be listening. This one app that I’m looking at says that if you were to listen for a couple months for just a half an hour daily, you could memorize a couple thousand words already!
That’s quite a lot for passive learning, but I still do recommend that as you continue learning the language, you listen to programs in that language. When you’re not driving, you should be using a combination of methods, such as watching those movies I was telling you about.
For right now, however, focus on vocabulary word lessons while driving, and you can expand upon that when you’re at home relaxing. You might try to learn the language subliminally while you’re sleeping as mentioned, too.
Learning a language, especially when not a child, is one of the most difficult things to do for many people. Once you do learn the language you’re going to want to keep using what you know and practice or you can lose what you’ve learned quite easily.
