'Bicycle safety film for children, shot on the streets of Oakland and Berkeley, California. Features numerous examples of safe and unsafe cycle riding, simulated accidents, and scenes of post-World War II East Bay streets and sidewalks.'
Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Bicycle safety is the use of road traffic safety practices to reduce risk associated with cycling. Risk can be defined as the number of incidents occurring for a given amount of cycling. In many countries both the number of incidents and the amount of cycling (expressed in kilometers, hours or trips) are not well known. Non-fatal accidents often go unreported and bicycle use is only occasionally monitored. Some of this subject matter is hotly debated: for example, the discussions as to whether bicycle helmets or cyclepaths really improve safety. The merits of obeying the rules of the road including the use of bicycle lighting at night are less controversial...
Safety equipment and strategies
Helmets
Helmet use varies from almost none in some regions to being mandatory for children to being mandatory for all cyclists. Helmets are required in most races. Helmets may help prevent head injuries, but laws that enforce helmet use have also been shown to discourage cycling.
Lights
Headlights and taillights may be mounted on the bicycle or worn by the cyclist. Bicycle lights can be powered by replaceable batteries, by internal rechargeable batteries, or powered by a hub, bottle or roller dynamo that produces electrical energy when driven by the rotation of the wheels.
Cycling lights are typically of lower power than those on motor vehicles, but well-designed lights are perfectly adequate for the lower speed of bicycles. The best bicycle headlights have beams shaped to efficiently light the road. These are also suitably conspicuous to other road users. In order to be effective, it is best for lights to be securely attached to the bicycle and properly aimed, not mounted on soft bags or loose clothing. In the US, state and local ordinances usually require this.
Audible signaling
Bells or other audible signalling devices are required equipment in many jurisdictions...
