NW Poll

Polite Driver Index

Wednesday, January 16, 2019by  PEMCO Insurance

​According to the 2019 PEMCO Insurance Northwest Poll, drivers in our area are becoming increasingly aggressive on the road, but most believe that their fellow motorists engage in even more rude or dangerous driving behaviors than they do.

How about you? Are you seeing or doing more aggressive driving than before? If so, why?

Seventy-nine percent (79%) of drivers in Washington and Oregon reported that they, personally, engaged in fewer than three aggressive driving behaviors within the past month. These same drivers said that they witnessed many more aggressive behaviors from other drivers on the road. About one-half in both regions (60% in Washington and 55% in Oregon) said that they have witnessed aggressive behaviors from other drivers at least five times in the past month.

Oregon: Frequency of Exhibiting Aggressive Behaviors (speeding, tailgating, erratic maneuvers, etc.)

In June 2018 and in November 2015 all licensed drivers in the state of Oregon were included in this research. This is a departure from prior years in which only those living in the Portland Metro area were included. This report compares the 2018 data to the November 2015 Oregon statewide data.

Compared to November 2015, Oregon drivers report engaging in about the same number of aggressive driving behaviors. In 2018 the average number of aggressive behaviors Oregon drivers reported is 1.9, compared with 1.2 reported in 2015. Over time, Oregon drivers report witnessing about the same number of aggressive driving behaviors also. The number of aggressive behaviors they witnessed from other drivers stayed about the same, going from 8.7 in 2015 to 9.1 in 2018.

Polite Driving Index

The Polite Driving Index is derived from two measurements: the total acts of politeness and the total acts of aggression:

Polite Driving Index = Total Politeness – Total Aggression

Since the Polite Driving Index benchmark was set in June 2009, Washington state drivers remain relatively more polite than they are aggressive. The index increased between 2009 and 2015, indicating drivers were becoming increasingly polite. That trend reversed in 2018, when Washington drivers report that, although drivers are still more polite than aggressive, they’re not as polite as they were five years ago.

The most dramatic difference is among males, where the polite driving index has decreased from 139 in 2015 to 121 today. Females, too, have seen a decline in their index. Among females, the index dropped from 144 to 136.

About the PEMCO Insurance Northwest Poll
PEMCO Insurance commissioned this independent survey, conducted by FBK Research of Seattle, that asked Washington and Oregon residents questions about driving habits and attitudes toward current Northwest issues. The sample size, 600 respondents in Washington and 600 in Oregon, yields an accuracy of +/- 4.1 percent at the 95 percent confidence level. In other words, if this study were conducted 100 times, in 95 instances the data will not vary by more than the associated error range.
