The Nakuru–Naivasha Highway is infamous as one of Kenya's deadliest roads, a reputation tragically reinforced by the recent death of former Lugari MP Cyrus Jirongo in a head-on collision. The accident occurred on a notorious blackspot at Karai, highlighting the persistent dangers of this busy transport corridor, especially during nighttime hours.

• Over 4,100 people have been killed on Kenyan roads this year, the highest figure in years, according to NTSA.
• The crash involving Jirongo’s Mercedes-Benz E350 and a Climax bus happened around 3 am in Karai, a section known for poor visibility and narrow bends.
• The Kenya National Highways Authority and NTSA have repeatedly flagged dangerous segments including Karai, Kinungi, Gilgil, Elementaita, and the Delamere stretch.
• The government launched the Rironi–Mau Summit Road project, expected to be completed by June 1, 2027, to upgrade the highway into a dual carriageway and improve safety.
