Levi Johnston Doesn't Like to Take It Slow

Finally, someone other than Bristol Palin is blaming Levi Johnston for pulling a quickie ... and this time it's cops in Alaska.

We're told an Alaska State Trooper nailed Johnston for driving 63 in a 45 back in October -- and fined the accidental Palin extended family member $155.

The good news: Levi has finally learned to use protection ... he was wearing his seat belt when he was pulled over.
