J. Trump State Park, with separate parcels called Indian Hill and French Hill. In July 2009, Diane Schuler of West Babylon crashed her van head-on into an oncoming sport utility vehicle (SUV) while driving south in the northbound lanes approximately north of the Pleasantville Road exit. Eight people, including Schuler and several children, were killed. The accident was the deadliest ever on the parkway, and the worst motor vehicle accident in Westchester County since 1934. Schuler was determined to have been driving under the influence of both alcohol and marijuana. The road, which has a lower accident rate than average for New York, was not considered to be at fault. Some changes were nevertheless made. Two large "Wrong Way" signs were installed on the ramp she drove down. Westchester County Executive Andrew Spano ordered that signage at onramps on the Taconic and other parkways in the county be checked to make sure "there can be no question of whether you're entering or exiting." The state legislature passed Leandra's Law, making it a felony to drive while intoxicated with a passenger 16 or younger, partly as a result of the accident. In the years 2009 and 2010, the existing "rustic" guide rail along the medians and edges of the parkway were systematically replaced with zinc-coated type guide rail. The existing "rustic" box beam, cable, and w-shape guide rail were replaced. According to data compiled by the National Highway Traffic Safety Administration, the Taconic was the second deadliest road in Dutchess County after US 9 between 1994 and 2008. New York State Police blamed travelers exceeding speed limits, wildlife crossings and trucks being directed onto the parkway by their GPS navigation devices. The state was planning to post more explicit signage making it clear that trucks are not allowed on parkways in New York. Exit list Intersections and interchanges were formerly numbered sequentially with a single letter prefix indicating the county, with exit numbers resetting at county lines. Intersection numbers were posted on small tabs attached to the intersection sign, as opposed to on gore signs as on other controlled-access highways. Numbering was not necessarily sequential, as some exits were removed or added after the parkway opened. From 2016 to 2018, NYSDOT added mileage-based exit numbers. At-grade intersections were not numbered, though their signage was improved. The Taconic, which is the state's longest parkway, previously stood out for its lack of exit
