My suggestion - when reporting an accident, have 3 icons in a row as follows to indication the location of the accident:

1 - Blocking Left Lane (icon is on left)
2 - Blocking All Lanes (icon is in the middle)
3 - Blocking Right Lane (icon is on right)

And optionally, have another 2 options for the accident is moved to the left shoulder or right shoulder. In fact, an added benefit would be to present this same set if icons as part of the notification. As people are notified, and if the vehicles have been moved, allow Wazers to indicate that the location of the blocked lane is changed.

This would be so valuable, as it would help us know which side of the freeway is clear so we can get on that side early.
