The National Transport and Safety Authority (NTSA) has opened investigations into two drivers of luxury cars who were filmed racing on the Nairobi Expressway. The viral clip shows them weaving through traffic at high speed.

In a statement posted on its X account on Monday, October 26, 2026, the authority condemned the stunt and asked members of the public to send it the vehicles' registration numbers and any other details about the drivers through direct message.

"These drivers not only put their own lives at risk, but also endangered passengers and other road users," NTSA said, adding: "We will investigate and take immediate, appropriate action."

What the video shows

The footage has been shared widely on social media. It shows the two vehicles, a Lamborghini and a Mercedes-Benz, pulling up side by side on the elevated toll road and waiting for a countdown before taking off. K24 Digital describes the cars as a Lamborghini Urus and a Mercedes-Benz GLE, while Kenyans.co.ke describes the second car as a Mercedes-Benz C-Class.

As the race goes on, the cars cut between other motorists' vehicles and overtake on the left. At one point a car comes dangerously close to another vehicle, and collision-warning alarms can be heard inside the cabin.

Both K24 Digital and Ghafla identify the drivers as two forex traders who are popular on social media, known online as Kenyan Prince and Graig the Billionaire. According to K24 Digital, a friend who rode in the back seat of one car said Sh500,000 was riding on the race. NTSA has not named the drivers, and neither man had publicly responded at the time of publishing.

Timing raises the stakes

The clip went viral a day after a church bus and a cement truck collided at Kanga near Mtito Andei on the Nairobi-Mombasa Highway on Sunday, October 25. The crash has so far killed 24 people. Preliminary findings by NTSA point to improper overtaking.

After that tragedy, NTSA asked the government to declare road crashes a national disaster, saying more than 5,000 Kenyans die on the roads every year. Roads and Transport Cabinet Secretary Davis Chirchir has also promised a crackdown on reckless overtaking, speeding and other violations.

Many road users online said the Expressway clip showed how some motorists still treat public roads as private racetracks, even as the country mourns.

What the law says

Under the Traffic Act, reckless or dangerous driving is a serious offence and can lead to fines, licence suspension or a jail term, depending on the outcome of a court case. Racing on a public road without authorisation is also prohibited. Authorities have not yet said what charges, if any, the two drivers could face.

The Nairobi Expressway is a 27-kilometre toll road running from Mlolongo, past Jomo Kenyatta International Airport, to James Gichuru Road in Westlands. Because it is a tolled road with controlled entry and exit points, investigators may be able to trace the vehicles even if the public does not come forward with the plates.

NTSA has in the past used viral videos to trace and suspend drivers of matatus and private cars caught breaking traffic rules. The authority says road users can report dangerous driving through its official social media handles and hotlines.
