CHICO — A host of new laws go into effect Friday, and the majority of them will affect drivers and roadway users.

One of the most significant is the so-called "move over/slow down" law. It requires motorists to move over one lane, if possible, when approaching tow trucks or other emergency work vehicles displaying flashing lights.

In most cases, the vehicles would be responding to the scene of a traffic accident or other emergency.

If an alternate lane isn't available, motorists are required to slow down to an appropriate speed as they pass.

Failure to follow the new law can result in a citation.

David Anderson, owner of Always Towing, said drivers endangering tow truck operators is a continuous problem. "I think this law is a good idea," he said. "A lot of people just aren't paying attention. If they get a ticket, maybe they'll start," he said.

"If we could get another lane between us and the traffic, it would be a good thing," said Ken Butler, owner of Browers Towing.

Also Friday, the California Public Utilities Commission will be able to crack down on charter carriers who operate buses on a suspended permit, or which have three or more liability insurance violations within a two-year period.

The new law was prompted by a charter bus crash near Colusa last year that killed 11 people.

Upon notification by the CPUC, the California Highway Patrol would be authorized to impound a bus for 30 days.

Another new law permits motorists

who use toll highways or bridges to have the toll billed to them based on a pay-by-plate system, or be deducted from an Automotive Vehicle Identification account.

Yet another law provides added penalties if a suspect assaults a city or county employee while working on a street or roadway project. A similar protection is already in place for state and federal highway workers.

Finally, starting Friday, it will be legal for people to ride a bicycle without a seat if the bike was designed by the manufacturer to be operated without a seat.

On July 1, 2010, a pilot program will begin in Alameda, Los Angeles, Sacramento and Tulare counties requiring people convicted of driving under the influence to install ignition interlock devices in any vehicle, including motorcycles, they may operate.

The IID's would have to be installed before the state will issue a restricted driver's license to the offender.

Also starting Friday, restaurants in California will be prohibited from cooking food with trans fats.
