Alcohol EffectsQuestion 24 of 100

Under California Vehicle Code §23152(b), a person 21 or older driving a non-commercial passenger vehicle is guilty of DUI if their blood-alcohol concentration is:

a.0.05% or higher
b.0.06% or higher
c.0.08% or higher
d.0.10% or higher

Explanation

Vehicle Code §23152(b) makes it unlawful for a person to drive a vehicle with a BAC of 0.08% or higher. §23152(d) sets a lower 0.04% limit for commercial drivers, and Vehicle Code §23136 imposes a 0.01% 'zero tolerance' rule for drivers under 21. A driver can also be convicted under §23152(a) for driving 'under the influence' at any BAC if impairment is shown. Servers should be aware that an average 160-lb adult reaches 0.08% with about 4 standard drinks in one hour.
