Visibility & Line-of-Sight Calculator

Legal Application: This tool models critical visibility factors in "failure to see" cases. Analyze sight obstructions, A-pillar blind spots, night visibility ranges, hill crest scenarios, and ADAS sensor coverage to establish whether a driver "could have seen" or "should have seen" the hazard or other party.

Legal Analysis

Visibility Assessment

INFO
Calculate visibility to generate analysis findings

Key Legal Considerations

DUTY OF CARE
Drivers must maintain proper lookout and adjust speed for visibility conditions
FORESEEABILITY
Was the obstruction or hazard something a reasonable driver should have anticipated?
ADAS RELIANCE
Over-reliance on automated systems may not absolve driver of negligence
