Let me elaborate a bit more. 23109(c) can be charged as either a misdemeanor or an infraction (your citation should have a check box indicating which). If it is the former then 23109(i) applies; otherwise, and pursuant to Penal Code section 19.8: VC 23109(c) charged as an infraction is subject to (base) fine "... not to exceed $250 ... ."... More specifically, and according to the Uniform Bail Schedule the base fine is listed at $75 which after adding penalties and assessments it adds up to $353.

Either way, and upon conviction, a 23109(c) will earn you 2 violation points on your driving record.
