Inspector General of Police Joseph Boinnet on Monday failed to appear before MPs to explain why the country is experiencing numerous road accidents.
Traffic Commandant Samuel Kimaru told the National Assembly Committee on Transport that the IG was attending a National Security Advisory Council meeting at the Interior ministry's offices.
The committee chaired by Pokot South MP David Pkosing wanted Boinnet to explain the breakdown in the coordination of traffic in the country which has seen rise in the number of fatal accidents.
The breakdown - according to Pkosing - contributed to lose of 507 lives in two months.
"If a disease killed 500 people, I am sure it will be declared a national disaster, " said Pkosing.
"Here we are talking of 507 lives lost in two months."
Members of the committee led by Mumias West MP Johnson Naicca claimed Boinnet's action amounts to contempt.
He demanded action against the police boss.
"I think the IG is unable to do the job. It is high time that the country gets another IG," said Naicca.
NTSA, in the August accident report, said 183 more people died on top of the 1,835 cases reported in August 2017.
