Comedian and actor Kevin Hart says he'll straighten up his act. And he's not being funny.

Los Angeles traffic police arrested the stand-up comic on "suspicion" of drunken driving early Sunday.

They observed him speeding down a freeway at 90 mph in his black Mercedes, weaving across traffic lanes and almost running into a gas tanker truck, the California Highway Patrol said in a statement.

When patrol officers pursued him, he took an off ramp and pulled over, police said.

"Mr. Hart had objective signs of intoxication and was unable to perform the field sobriety tests," the statement read.

The comedian later tweeted: "When the cop asked me to take the sobriety test I said 'WHY WASTE OUR TIME ... I'M DRUNK MAN.'"

Police booked him into jail and held him on a $5,000 bond.

"This is a wake up call for me, I have to be smarter & last night I wasn't ... everything happens for a reason," he tweeted Sunday.
