Kim, North West, Khloe, Kylie Car Accident in Montana

1:10 PM PST -- Cops tell us there was no damage to the Kardashian's vehicle -- a black Yukon GMC -- and a motor carrier service called the slide-off into police.

We're told the incident was part of a number of similar accidents that happened today due to the icy roads ... and the family was calm when cops arrived. No citations were issued.

Khloe Kardashian skidded on an ice-covered Montana road and dangerously crossed into oncoming traffic, eventually landing in a ditch with Kim, North West and Kylie on board.

We're told the girls were driving in Bozeman, MT Saturday morning when a semi-truck drove by their car and kicked up a ton of snow, hitting their windshield and apparently blinding Khloe.

Apparently Khloe couldn't see and began swerving, right into a patch of black ice.  The car then spun out of control, crossing oncoming traffic and ending up in a ditch.

We're told cops came and everyone's ok.  

The accident comes 2 weeks to the day after Bruce Jenner got in his fatal car crash.

Kim posted this pic on Instagram afterward ... seemingly making reference to the accident.
