Charles Barkley was legally drunk when Gilbert, Ariz., police arrested him for DUI on Dec. 31.
Test results released Friday show that Barkley had a blood-alcohol level of .149, almost twice the legal limit of .08 in that state, the Associated Press reports.
Police say they noticed Barkley, 45, running a stop sign in the Old Town section of Scottsdale at about 1:30 a.m.
Barkley was issued a citation for driving while impaired and released pending the results.
For a first offense, someone found guilty of the charge Barkley faces might expect between one to 10 days in jail, the suspension of driving privileges for 90 days, and a fine of $1,000 or more, police said.
