Motorcycle Filtering Tips for the City

Continuing on from my previous post on motorcycle filtering tips on motorways and dual carriageways, today I’m going to talk more specifically about filtering in the city and more suburban roads (that’s lane-splitting for US readers). In the city, one needs to be far more alert and aware of upcoming hazards. There is much more to watch out for compared to the motorway, lanes tend to be tighter, traffic is turning and pulling out of everywhere, you have to contend with delivery scooters, cyclists, pedestrians and all their related street furniture and road markings. After riding through the city a number of years, filtering has become almost second nature, below are some filtering tips and advice I have accumulated.

Filtering Law – What’s Legal and What’s Not?

As mentioned in my previous post, it is legal to filter in most instances. Below are some instances where the highway code says you must not do something and are thus making filtering illegal in these cases. You must not:

  1. Cross any unbroken white lines, whether they are separating lanes, surrounding a crossed hatched area, or separating off a cycle lane. An exception is if needing to negotiate a stationary hazard, cyclists, horse or slow maintenance vehicle and it is safe to do so. (See Highway Code section 129 and 165)
  2. Filter past the vehicle nearest a pedestrian crossing where there are zig-zag markings on the road. (See Highway Code section 191)
  3. Filter in a bus lane, unless it has been specifically designated for motorcycle use or outside its hours of operation. (See Highway Code section 165)
  4. Enter an area designated for cyclists with an Advanced Stop Line (ASL). London boroughs have recently started enforcing this!
  5. Filter past the nearest vehicle to a pedestrian crossing. (See Highway Code section 165)
  6. Filter on the wrong side of a keep left sign/ballad.
  7. Filter so as to cause another vehicle to brake, swerve or take evasive action to avoid you.

Below are instances that the Highway code says you do not or should not, thus not illegal, but will potentially be held against you when assigning liability following an incident:

  1. Filter on the nearside in a cycle lane (with broken boundary).
  2. Filtering on a cross-hatched area surrounded by a broken white line See Highway Code section 130).
  3. Change to the lane on the left to overtake a vehicle (See Highway Code section 150).

In general, the best advice is to keep speed low, cover your brakes and look far ahead. No, even further ahead! Hazards can appear quickly and split-second reactions are crucial. It’s imperative to look ahead, read the road and second guess what the traffic is going to do. ‘Why’s that taxi slowing and pulling into left – because he’s going to pull a U-Turn – ahh!’

Speed-wise, a good rule of thumb is not to filter more than 10-15mph faster than the neighbouring traffic and not to filter at speeds above 40mph.
