Feds Postpone Hybrid and EV Warning Noises Until Next Year
Federal regulators have postponed rules to require hybrid and EV carmakers to add audible warnings to their cars to alert nearby pedestrians, bicyclists and visually impaired people, Reuters reported.
The audible warnings would be installed on cars made by Ford, Honda and Toyota and be activated when those cars are traveling slower than 18 mph. According to the report, the National Highway Traffic Safety Administration says hybrid and EV cars are 19-percent more likely to be involved in a pedestrian crash when compared to gasoline cars. The rule could prevent 2,800 crashes with pedestrians.

NHTSA: Pedestrian and Cyclists Crash Rates Higher For Hybrids
An NHTSA report [ PDF] on the “Incidence of Pedestrian and Bicyclist Crashes by Hybrid Electric Passenger Vehicles,” concludes that hybrid-electrics (HEVs) have a higher incidence rate of pedestrian and bicyclist crashes than do internal combustion-only (ICE) vehicles in certain scenarios. And based on the report’s conclusions, it looks like the relative silence of hybrids running in electric-only mode is to blame for the higher accident numbers.
. . . pedestrian and bicyclist crashes involving both HEVs and ICE vehicles commonly occurred on roadways, in zones with low speed limits, during daytime and in clear weather, with higher incidence rates for HEVs when compared to ICE vehicles. A variety of crash factors were examined to determine the relative incidence rates of HEVs versus ICE vehicles in a range of crash scenarios. For one group of scenarios, those in which a vehicle is slowing or stopping, backing up, or entering or leaving a parking space, a statistically significant effect was found due to engine type. The HEV was two times more likely to be involved in a pedestrian crash in these situations than was an ICE vehicle. Vehicle maneuvers such as slowing or stopping, backing up, or entering or leaving a parking space, were grouped in one category based on that these maneuvers are potentially have occurred at very low speeds where the difference between the sound levels produced by the hybrid versus ICE vehicle is the greatest.
