The impact of this issue can be reduced by changing the game resolution as follows.
1600x1200 (Russian title) or 1280x960 (English title) assuming your graphics card supports these resolutions.
If you must use resolutions of 1024x768 or less, avoid colliding with cars and objects as you may experience game breaking physics.
This often occurs after changing seats with other drivers many times in a short period.
Change seats again or call 911 (use caution as changing seats can cause other issues, see bugs below)
This makes it impossible to arrive at the destination first. No known fix.
A workaround is to initiate a trucking race, finish it in any position and the remaining unemployed truckers (assuming they participated in the race)
may be for hire after the race. This workaround is not guaranteed.
(This may be triggered by starting the race directly or by changing seats).
While often considered an in-game mechanic, this is very likely a memory leak. No known workaround.
