There are many factors that affect a person’s blood alcohol concentration (BAC) when drinking. The blood alcohol level charts below estimate the BAC effects of drinking based on the person’s: gender, weight and type of drink. Other factors can also affect BAC levels, such as: what food is in your stomach, your liver function and how much water you have consumed.
The California BAC limit for legal driving is:
- .01% or higher: If you’re under 21 years old or are on DUI probation for a prior DUI conviction
- .04% or higher if:
- You are driving a passenger for hire vehicle with a passenger (i.e. Uber, Lyft and taxi drivers) effective 7/1/18, or
- You hold a commercial driver’s license (CDL). This limit applies whether you are driving a personal or commercial vehicle.
- .08% or higher: If you’re an adult, 21 years of age or older and hold a standard California driver’s license with no restrictions.
The BAC levels California defined in the charts below are for adults aged 21 years or older that are not commercial license holders:
