If you text or hold your cellphone while driving or riding your bicycle, you might face a steep increase in fines.

The state Senate on Monday approved 24-12 a bill that would raise the base fine of a driver’s first violation to $50, which with fees would total about $300 a ticket, and the base fine for subsequent violations to $100, which with fees would be about $500. The bill also would add a penalty point on motorists’ driving records for repeat violations. The measure also would for the first time apply the state’s cellphone and anti-texting laws to bicyclists, but bicyclists would only pay $20 total for a first offense and $50 total for subsequent and would not receive points on their driving record.

The bill by state Sen. Joe Simitian, D-Palo Alto, is similar to once he introduced in the last legislative session, where it also passed the Senate but got killed in the Assembly. With Monday’s Senate passage, his new bill now goes to the Assembly.

Simitian wrote California’s original cellphone law, which took effect in July 2008. In promoting his latest bill, Simitian said CHP data from the first year of the law found a 20 percent drop in fatalities and collisions, or at least 700 fewer deaths and 75,000 to 100,000 fewer collisions.
