Masomo Monday – TSD ( Total Stopping Distance)

Total Stopping Distance is a sum of 3 parts.
1. Perception Distance
2. Reaction Distance
(1&2 are referred as Thinking Distance)
3. Braking Distance

Actual thinking distance varies according to the speed of the bike, your physical and mental condition, your attentiveness and whether or bit you were expecting something to happen.

Good anticipation gives you more stopping distance. Anticipation is much more important than fast reactions. It takes much longer to react to unexpected events than to expected ones – you need less thinking time if you are anticipating events and not just reacting to them.
In the video attached, the rider is not exercising restraint speeding on a two way country road , putting himself and others at risk.

1. Perception Distance
He did not anticipate any hazard in any of the near blind corners on this road, the presence of the truck catches him by surprise. He was in the wrong lane position as he came into the turn, limiting his view through the out the corner. He is still moving and this eats into his braking distance.

2. Reaction Distance
His reaction time is delayed, he takes time to process the truck coming into view. He is still moving eating into his braking distance.

3. Braking Distance
At the speed he is still travelling at his braking distance is limited. He grabs hard onto his brakes. He has lady luck on his side, and squeezes between the truck and the pavement. And his ABS kicked in which prevented his wheels from licking and the bike going into a skid. The scattering noise you hear is the ABS constant release at lock point to brake again. Though in review ABS did increase his braking distance.

What should he have done different to avoid putting himself and others at risk?


Masomo Monday- Road Rage By L. Monyenye

Today’s Masomo Monday is a contribution from L. Monyenye on road rage.

On 25 Dec last year on the Githurai 44 route, a personal car was involved in an accident with one of the buses that plies that route.
Out of rage, they confronted each other and the driver of the personal car was badly injured as a result of the confrontation.
From the incident, I learnt that:
1. Violence does not solve anything.
2. Just because you are involved in an accident doesn’t mean you need to engage the other party.
3. At times walking away, does help. Especially if the other party (or you) appears irate.
Then I was wondering



– Have you witnessed road rage?
-Or have you been a part of it?
– What did you do/learn?
As you answer her questions, have a look at this article on an unfortunate incident in the UK.
How do you handle ‘cagers’ who seem to ‘take offence’ to your overtaking, lane splitting or mere presence on the road for whatever reason?
