Only 38 percent of the drivers said they are likely to drive during the night, and 39 percent said they are likely to drive on freeways. Participants also answered questions regarding factors of driving that have become more difficult as they have gotten older.
"One of the most difficult things for them is identifying the speed and distance of oncoming traffic," Dissanayake said. "This is important for making a left turn, and looking at the crash data, we see a lot of left-turn crashes."
The participants also said they have difficulty and feel less comfortable making sudden, unexpected stops while driving, as well as merging and changing lanes. Fifty percent said they would like to avoid high-traffic roads, as well as freeways and two-lane undivided highways.
One of the challenging situations that could be improved is the safety at intersections, Dissanayake said.
"In areas where there are more older drivers, I think we should always look at the possibility of having the green arrow indication at left turns," Dissanayake said. "Additionally, for driver education perhaps we need to have a closer look at the driver license renewal process, such as its frequency and what is covered."
She said the fonts and sizes of road signs also could be further improved to ensure older driver safety.
"As the older population gradually increases in the United States, so will the number of older drivers," Dissanayake said. "We need to be taking steps to improve their safety while driving, which also would be beneficial to all road users."
