A motorist rammed another from behind near Githurai 45 and they ended up painting the busy highway white colour.
The morning accident caused a traffic snarl up on the side towards Thika. It is said one of the drivers was overtaking but lost control of his car and hit another that was carrying paints.
The paint spilled on the road drawing onlookers while motorists were left confused wondering if it was lethal substance.
Hundreds of motorist who have driven over the paint have ‘painted’ the road further towards Githurai 45, leaving it looking a snow field.
