Intersection Safety
Older Driver Crash Statistics
Per mile traveled, fatal crash rates increase markedly after age 80
Between 2002 – 2012, approximately 1 out of 5 fatal crashes in Maryland involved drivers over the age of 65
Only about 5% of fatally injured drivers ages 70+ had BAC 0.08 percent, compared with 17% for ages 60-69 & 43% for ages 16 to 59
Crashes at intersections account for about 39% of fatal crash involvements among drivers ages 80+ (compared to 21% for total population)
10
Intersection Safety
5 Top Crash Types for Older Drivers
Turning left at an intersection with stop sign
Turning left at an intersection on a green light without a dedicated green turn arrow
Turning right at a yield sign to merge with traffic at speeds of 40 - 45 mph
Merging onto a highway from a ramp that has a yield sign
Changing lanes on a road that has four or more lanes
11
Intersection Safety
4 Most Common Older Driver Errors
Not noticing potential conflicts or
traffic signs and signals
Misjudging gaps when crossing traffic
Moving or stopping the vehicle too
slowly
Conducting a visual search poorly.
Before an Intersection Crash
12
Developing Maryland’s Systemic
Intersection Safety Implementation Plan
Improve substantial number of targeted
intersections which have severe crashes
Rely on low-cost, simple but proven and
effective countermeasures
Improve 3-6% of intersections that have 25-
45% of statewide intersection crashes
Higher overall cost but greater impact in
terms of statewide levels of lives saved
