Archives For overtake
I’m sure we have all been in a situation where a driver behind us has blasted their horn because we are ‘in their way’.
I tried to do the similar whilst on my bicycle, I got up really close behind another vehicle, dinged on my bell really loudly to show my frustration, unfortunately they couldn’t hear it due to them singing along to a dodgy song from Heart Radio. When they finally pulled over and stopped, I cycle passed shouting my frustration, telling them they can’t drive here and they should be on the motorway. The driver was clearly startled by this as they quickly got out of their car and ran into the post office with a letter. A letter which I’m presuming was a written apology to me for being in me way.
Sounds crazy eh?! But that is pretty much what happens to cyclists. Drivers expect us (cyclists) to bow down and pump their tyres up with our mouths as they pass. They drive close behind us and blast their horns if we are stopping them from progressing to the back of the next queue. As they pass they shout out of the window that we don’t pay ‘road tax’ and that we should be on the pavement.
It’s bullying behaviour and shouldn’t be accepted on our roads. Look after the more vulnerable road user.
Note: Some things said in this post are not strictly true.
All cyclists have experienced a close pass from another vehicle. It’s an uncomfortable experience and the larger vehicles can cause major issues due to the turbulent air that they throw off. Cyclists need to be given lots of space, we need to move around road hazards such as pot holes and we aren’t surrounded by metal.
Some states in the US and a few countries have a specific passing law. Usually 3ft or 1m space that overtaking vehicles must give to cyclists. In the UK we don’t have a specific law and the highway code suggests that you should give as much space as you would a car, I have commented on that before.
I see some problems with passing laws
- How do you measure the distance?
- Larger differences in speed require larger passing distances.
The DFT name the space a cyclist requires the dynamic envelope. The Cycle Infrastructure Design (CID), Department for Transport Local Transport Note 2/08, October 2008. Section 2.2.2 states that the dynamic envelope of a cyclist on the road may be taken as 1 meter. As the name suggests, the dynamic envelope changes depending on the situation but the basics of it is the required space a cyclists needs to keep in motion. Corrections are made to avoid hazards and to keep balance.
When a vehicle overtakes a cyclist, the space they should leave you is in addition to the dynamic envelope. The DFT recommend that in addition to the dynamic envelope of 1m, cars passing at 30mph should add another 1.5m when passing. In total that equates to 2.5m from the cyclist (this distances is measured from the wheel of the cyclist to the edge of the car). How many drivers do we see passing cyclists at such a distance?
The DFT recommends that larger vehicles (buses, HGVs) should give a total of over 5m when passing a cyclist at 30mph.
The distances which drivers give cyclists needs to be increased in situations like hills, cyclists will be going at a much lower speed and keeping a straight line can be more strenuous. In these cases more space will be needed.
To cover one of my concerns, as the difference in speeds increases then more space is required, if a cyclist is traveling at 10mph and a car passes at 3ft at 60mph then the turbulent air will push them off their course and could well blow them over if they are not prepared for it.
How can we measure passing distances whilst on the road? This is always going to be a problem, one persons 3ft is another persons 2ft and being on a bicycle the two will feel very different, the two will probably be very similar when you are surrounded by metal. In the case of reporting it to the police or speaking to the driver about it, this will be the same old situation which we are used to, your word against theirs.
I have a ‘litmus’ test for close passes, I’m normally aware of when they will happen, I stick my arm out as if i was indicating, if i feel a vehicle brush against my arm then I know the pass is about to be too close and I can move over to the left a little bit to give me more space. My arm is a little under 3ft so if I can touch your vehicle as you pass me then you are too close. I’ve noticed so far that this gives the drivers a panic and they either stop their over take or they move further out, it has the added bonus of making you look like you are turning right.
The guidelines for passing distances that the DFT state are well over what any laws are in other countries and anything that is proposed in the UK. I can’t see a 3ft law being brought into the UK whilst a DFT recommended 30mph passing distance is over 2.5x bigger. The minimum 20mph passing distance that the DFT recommends is 2 meters. Because of this I’m mentally against any passing laws that state 3ft as the minimum.
