Traffic in Los Angeles can be horrific. If you are traveling to Los Angeles and plan on renting a car, you have to be prepared for the traffic. It can be brutal at any time of the day or night as you can see from this picture. I was in my car, it was about 11pm and I was literally stopped on the freeway because of all the traffic (see my speedometer?).
There is so much to see in Los Angeles but you must factor traffic into your plans. For instance, Hollywood to Disneyland is about 32 miles. That is about 40 minutes of travel time. However, in crazy L.A. traffic that can easily take you almost 2 hours so please keep that in mind when you are trying to get from one place to another!
Just one of those tips to help you travel better.
