Road Signs in Kenya – Comprehensive Guide to Traffic Regulations

Updated on May 2, 2024 – Revised the article to include detailed information about the four categories of road signs in Kenya, namely Class A (Regulatory Signs), Class B (Warning Signs), Class C (Traffic Lights), and Class D (Carriageway and Kerb Markings). Added comprehensive lists and explanations for each category, enhancing the reader’s understanding of road signs and their importance for road safety and traffic management.

Driving in Kenya, like in any other country, requires adherence to essential road signs to ensure safety for all road users. Safety is a familiar word when we talk about machinery, equipment, and vehicles.
In the lower primary, I remember we were taught how to cross the road. We learned the meaning of the traffic lights (colors), and what to do before we cross the street.
It was something like this: Look right, look left and look right again then go ahead to cross the road. I loved how we sang it out, beautiful memories.

Importance of Road Signs

Road signs serve as visual cues that communicate vital information to drivers, pedestrians, and other road users. They help in:
  • Ensuring Safety: Alerting drivers to potential hazards, speed limits, and regulatory requirements.
  • Providing Direction: Guiding drivers to their destinations through clear directional signs.
  • Regulating Traffic: Managing the flow of vehicles and pedestrians at intersections, roundabouts, and other key points.

Have you ever noticed that road signs come in different shapes and symbols? It can be confusing, right? But don’t worry, they’re actually pretty simple once you understand them.

In Kenya, road signs are divided into 4 categories. Each category has its own set of signs with specific meanings. These signs are designed to be easy to recognize while driving. So, what are these four categories and what do they mean? Let’s break it down:

  • Class A – Regulatory signs.
  • Class B – Warning Signs.
  • Class C – Traffic light signals.
  • Class D – Carriageway markings and Kerb Markings.

Note: Signs on the road are there to keep everyone safe. That’s the main reason they exist. So, everyone needs to understand what they mean.

Class C – Traffic Lights

Traffic lights have different signals that tell drivers what to do at intersections. These signals are red, green, and amber. Drivers must follow these lights to keep traffic moving smoothly and avoid accidents.

Here is a list of common traffic lights used in Kenya:

  1. Red Light: Indicates that drivers must stop. It is usually displayed at intersections and pedestrian crossings.

  2. Green Light: Indicates that drivers can proceed, but they must yield to pedestrians and vehicles with the right-of-way.

    • Red Arrow: Prohibits turning in the direction of the arrow.

Note: It’s important to follow these rules to stay safe on the road and prevent accidents. Sometimes, you might see other lights with arrows that help direct traffic. For example, a green arrow pointing left means you can turn left even if the other lights are red. But if the arrow is red, you have to stop before turning left.

  1. This is quiet good.

    However it would be helpful for revision if you put explanations/description of each sign as you have done for class A.
