California is more vague with their DUI convictions that most states, but that doesn’t mean that it’s more lenient. California has laws, such as “implied consent” and “zero tolerance” for driver’s under 21, that make standardize some punishments for DUIs. A driver can be arrested for a DUI if they are operating a vehicle above their legal limit set for that state. The legal limit in Texas is as follows: Standard, non-commercial drivers: 0.08 Commercial drivers: 0.04 Drivers under 21: 0.01 Penalties, Fines, & Suspension
