Impeding in F1 is typically seen during practice and qualifying, as all drivers are generally pushing during the race.

In simple terms, impeding is when one driver unduly blocks another driver – causing them to abandon a lap or take action to avoid a shunt.

If a driver has completed a fast lap in qualifying and is on a cool-down lap, he will be going slower than normal and the other driver, on a flying lap, is forced to back out to avoid a collision. 

Drivers not on a flying lap must make every effort to stay off the racing line and penalities will be haded out if warnings are not followed.
