Multi-lane highway discussion:

[JBusch8899]

....my gf says it's illegal to pass someone on the right (say, on a three lane freeway passing someone cruising in the middle lane). I say BS. Thoughts?

Buy her a dinner and apologize because if memory is correct, passing on the right is a violation.

IC 9-21-8-6
Overtaking and passing on the right; conditions
Sec. 6. (a) A person who drives a vehicle may overtake and pass upon the right of another vehicle only under the following conditions:
(1) When the vehicle overtaken is making or about to make a left turn.
(2) Upon a roadway with unobstructed pavement of sufficient width for two (2) or more lanes of vehicles moving lawfully in the direction being traveled by the overtaking vehicle.
(b) A person who drives a vehicle may overtake and pass another vehicle upon the right only under conditions that permit overtaking upon the right in safety. Overtaking upon the right may not be made by driving off the roadway.
As added by P.L.2-1991, SEC.9.
