What should you rent for a car when traveling around Europe? Here are a few suggestions that may help you.
Drive what the locals drive. This probably means a small car with manual transmission. Having said that...rethink the number and size of your bags.
Drive as the locals drive. In the UK it will be on the other side of the road. For the rest of Europe it will be the same as the US. Keep in mind in Germany you are required to drive in the right lane unless passing. And don't assume you can turn right on a red light. Know what other countries may have as laws as well.
Learn to read the signs. You need to understand the road signs if you are going to be driving in Europe. Auto Europe is a popular rental can company that has an online pictorial of signs. Remember distances will be posted in kilometers, not miles. Gas is sold by the liter.
