A dozy driver who called police to report a drunk motorist was arrested himself – when cops discovered he was also sozzled.

The bizarre incident happened at junction 25 of the M1 in Derbyshire, U.K., following a minor collision between a Peugeot and a Fiat.

One of the drivers involved called police to report the other motorist who he suspected of being drunk.

“Forgetting he is also drunk. Both arrested. One blew 40 and the other 78. Charged to court.”
