# Distance While Passing Vehicle Occupies Left Lane

Written by Jerry Ratzlaff on . Posted in Civil Engineering

Passing distance, abbreviated as $$d_2$$, is the distance traveled by the passing vehicle while in the left lane.

## Distance While Passing Vehicle Occupies Left Lane formulas

 $$\large{ d_2 = \frac{ \bar {u} \; t_2 }{ 0.68 } }$$ $$\large{ d_2 = 1.47 \; \bar {u} \; t_2 }$$

### Where:

$$\large{ d_2 }$$ = distance while passing vehicle occupies left lane

$$\large{ \bar {u} }$$ = average speed of passing vehicle

$$\large{ t_2 }$$ = time the passing vehicle occupies the left lane
