When I went to see my sister and her family in Boston and borrowed their
car, they warned me about school buses. The red lights apply not only to
traffic behind the bus which is banned from overtaking but also to oncoming
traffic which is not allowed to pass the front of the bus if the red lights
are flashing.

Frustrating, but probably a good idea. At least in America they have the
concept of part-time speed limits: many schools seemed to have a 35 mph
limit in force for most of the day but a 25 or even 15 during very specific
arrival and departure hours. In the UK, we'd probably impose a blanket
24-hours-a-day 20 limit :-(

I would like to see part-time speed limits here, and also I would like
to see limits of 25mph and 35mph where appropriate, rather than the
steps in 10. On many roads, the speed limit should be 25mph but instead
they reduce it all the way down to 20mph which is far too slow.
