A

 Los Angeles is always a popular holiday destination. To fully enjoy your travel there, you should know its food, weather, and also traffic. While driving in L. A. is similar to that in other areas, there are a few specific rules to note.

HOV lanes (车道)

On many L. A. freeways, one or more lanes at the far left are used as high-occupancy vehicle (HOV) lanes. They usually have limited access and you can only enter or exit where there is a break in the double yellow line. Most HOV lanes require a minimum of two people in the car; some require three. Vehicles towing trailers (拖车) are NOT allowed in the HOV lane, regardless of how many people are in them.

Toll (收费) lanes

On certain freeways, the HOV lanes are double-purposed as toll lanes for people driving alone who have a FasTrak, an electronic toll collection system. Therefore, you also have to have one in that lane as a HOV, which is inconvenient if you’re just visiting. FasTrak is in effect on parts of the 110 freeway between the 405 and 10 freeways, and on parts of the 10 freeway east of Downtown L. A.

Cell phones

It is against the law to talk on a cell phone while driving without using a hands-free device. Holding a cell phone to your ear while driving will land you with a ticket.

Alcohol

Driving under the influence is taken seriously in L.A. The legal blood alcohol limit is 0.08%, but you can be charged with lower levels if they show you can’t function normally. Placing an opened bottle of alcohol in the passenger area while driving (or sitting) is illegal. Any opened container of alcohol has to be transported in the trunk.
