Dazzled by Headlights or the Sun ? Stop !

There have been many recent cases where drivers that drive while blinded by low sun have been acquitted of dangerous or even careless driving. Judges are ignoring the Highway Code when sentencing, and instructing juries to ignore it when deliberating the verdict.
If nothing else, this is unnecessary tautological duplication.
93 Slow down, and if necessary stop, if you are dazzled by bright sunlight.
6. Hot weather ...
237 ... If you are dazzled by bright sunlight, slow down and if necessary, stop.
It seems that we have no protection when on east-west roads after dawn or before dusk under UK case law. Perhaps there should be a curfew ?

Fog is already an accepted excuse for bad driving, so I wonder which universally-encountered weather conditions will be blamed for bad driving next ? Ice, Snow, Rain, Wind, Night, Cloud ?

The principle used to be Highway Code 126
Drive at a speed that will allow you to stop well within the distance you can see to be clear.
Pro Tip : If a car's number plate appears to be lit up, you are directly between them and the sun, so you are invisible.

Really, I would advise not using the roads when the sun is low. Extreme but safe !

Even slowing down is dangerous.
RAF Northolt Station Commander killed on A40 - [ Road Justice ]
"He was dazzled by sunlight, he slowed down and moved to the slow lane when other drivers were flashing their lights to say has driving too slowly, and that he was looking out for motorcyclists overtaking him at the time of the crash. He drove into the back of Group Captain Tom Barrett OBE, who was cycling"

Space Lemmings - Peer Pressure - Race to the Bottom

Space Lemming courtesy of lemnet.tripod.com
There are two tribes of road users, each of which thinks the other is dangerous - the fast and the slow.

Slow motorists often say they feel pressured to drive badly (eg speeding) by other motorists, specifically the one behind them.
  • Fast motorists say it is the slow motorists (not just cyclists) that are dangerous, because they get in the way, and even get them angry, 'forcing' them to drive badly.

There's more to life than not being dead ...

In safety statistics, analysts often use KSI (Killed or Seriously Injured) statistics.
Main reasons :
  1. Numbers killed often are, thankfully, too low for any statistically-significant conclusions to be drawn until many years have passed.
  2. Serious Injuries are usually about ten times more frequent, and often life-changing. So taking measures to reduce them is arguably just as important as reducing fatalities.
  3. Many other factors affect whether a casualty dies :
    • Vehicle engineering - crumple zones, airbags, seat-belts, safety glass
    • Emergency service response, particularly Air Ambulances
    • Medical care in hospital
Further than that, there are many 'Quality of Life' issues that are worth considering.
  • Perceived Safety
  • Improved lifestyle
  • Community well-being
  • Stress and Mental Health

Obstruction ?

In the early days of motoring, there was a law that every vehicle had to be preceded by a man walking with a red flag, and the vehicle had to stop when he waved it, to let horse-drawn traffic past safely.



One father has tried using his car to make it safe for his son to walk to school, as part of a campaign for a footway.
Could be a useful tactic for a Critical Mass ride ?

'Police advised him against this course of action for safety reasons.
'Officers have advised him that he is at risk of causing an unlawful or wilful obstruction should he continue to do this.'

Note that the police are fearful that other motorists might overtake unsafely. Pandering to the lowest level of incompetence can only encourage bad drivers.

Safety Theatre

No, I don't mean dramatic productions in schools to reduce risk to children , wonderful though that is !

I mean taking steps to make things look safe, but which have little or no beneficial effect in practice.

Googling "safety theatre" finds (mostly ? ) only the theatricals, but the American "safety theater" works.
The term Security Theater is wider-known, among conspiracy theorists at least.

It's questionable which things are effective and which not - the list below is neither definitive nor complete. It's part of the definition of 'Safety theatre' that we can't tell which measures are effective.

Obedience and Blame

The number of official contributory factors present in car-bike collisions are similar for cyclists and drivers.
Some factors are arguably bigger than others - I don't know if they were weighted.
The full report runs to 60 pages.
Slightly more contributory factors for cyclists, but I would guess it's not statistically significant.
Since the motorist is (almost?) never the fatality, that may introduce some bias. It would be interesting to exclude cases where the cyclist was unable to give a statement before dying.

Of course, risking your own life is not at all the same thing as risking anothers' !

The top factor was 'failed to look properly' for both sides, in about 30% of cases.

Overtaking - Roles and Responsibilities

Distance beside




Needs specific minimum space law ?

The Highway Code is not all enforced.
Lifting a finger - [ Pedaller ] asked police to discourage unsafe overtaking on bends.
"Rule 166 of the Highway Code states – DO NOT overtake if there is any doubt, or where you cannot see far enough ahead to be sure it is safe ... 
Accordingly the drivers overtaking you in contravention of this rule do not commit an offence per se and so it would not be a matter in which the police would intervene."
Perhaps that should be
"You MUST NOT overtake if there is any doubt ..."
 There was an ePetition
Clearly distinguish safe and unsafe overtaking of cyclists in law by establishing a 1.5m rule.
It only gained 231 signatures, I don't know how widely it was publicised.

Traffic Calming - Pedestrian Refuges

Motorists Please do not overtake cyclists through pedestrian refuge
You would think a council would re-think dangerous features, instead of erecting 9-word signs.


Pedestrian refuges are certainly an aggravating factor when motorists want to overtake cyclists.
I would be interested to know if they are actually useful to pedestrians, and whether they have a positive or negative effect on overall safety. I suspect that their only effect is to bring traffic speeds down, but at the cost of cyclists' safety.

The Highway Code in 100 words


The Highway Code in 100 words was an exercise in reducing the bloat and distilling the essential spirit of the Highway Code, when it was last published in 2007.
It came from a pro-speed, anti-camera motoring campaign group's forum, but is none the less interesting for that !

I, for one, welcome our new Google overlords


more ...

Google's driverless cars have clocked up 700,000 miles around California by late April 2014 - with only two accidents : one occurring in 'manual' mode , one was rear-ended while stopped at lights.
I guess that puts the algorithm in the top 5% of good drivers, but doubt if accurate statistics for humans exist!
