SEE notes: Cage approaching your path from side street.
Vehicles approaching your road from a side road. If you are not planning to stop at the intersection, look for signs that the car intends to stop. Also check if he is likely to turn right.
Things to look out for on the cage: turn signals, lane change into turn lane, car hood dips as brakes are applied, car hood rises as car accelerates, wheel turn without deceleration.
Driver danger signs: distraction with object, face turned down towards object on dash or in lap, face turned towards passenger in conversation.
Consider the possibility that the driver has not seen you and might not yield, or might run a light or stop sign.
Check if there are any vehicles or other obstructions that might block the driver's view of you.
Check for sirens or emergency vehicle activity.
Are there any vehicles between you and the approaching vehicle that you can move behind as a shield?
Consider if the car appears not to be stoping, or planning to turn right into your lane or an adjacent lane.
Evaluate if the driver has seen you.
Evaluate possible escape routes or blocking vehicles between you and the approaching vehicle.
If the car appears not to be stopping, or has not seeen you, consider moving to an escape route previously evaluated, change speed, or initiate crash avoidanc/evasion mode.
If the driver is distracted, evaluate his potential to drive across you, and consider additional active conspicuity measures.
Consider changing lane so as not to be in the rightmost lane, for a car turning from your right.
Consider using a vehicle as a shield. But be aware that the shield vehicle may stop. A colleague of ours once took off from a stoplight, with a truck to his left that he was using as a shield. The truck driver saw a red-light-runner coming from his left, and jammed on. Our friend didn't stop as quickly as the shielding truck did, and was taken out by the red light runner. Bear in mind that, even from as little as 10 MPH, your stopping distance is approximately 13.4 feet, if you include reaction time and braking distance. As you probably can't see your shielding vehicle's brake lights, your stopping distance might even be longer. That 13 feet is enough to lose your shield and be in a very dangerous situation.
When using a vehicle as a shield, especially when taking off, position yourself a little behind, so you can see the shield vehicle's brake lights and so you have enought time and space to stop if the shield vehicle does.
Flashing lights and/or horn might alert an inattentive or distracted driver.
Crash avoidance/evasion is covered in it's own section.
Changing position or speed might provide additional escape paths.
