Hundreds of motorists were stranded for over 10 hours on the Nakuru–Nairobi Highway after a massive traffic jam began on Thursday, August 28, at 8:30 PM. The Kenya National Highways Authority (KeNHA) confirmed the gridlock stretching between Naivasha and Kikopey, urging motorists to use alternative routes.

• The congestion was attributed to lane indiscipline, an unusually high volume of vehicles, and attendees departing the National Youth Service (NYS) pass-out parade in Gilgil.
• KeNHA expressed regret and is working with traffic police to ease the situation, while urging drivers to observe lane discipline.
• Long-distance bus companies have issued advisories due to delayed departures and arrivals, affecting even school students returning for reopening.
