Final answer:
You must report a collision on-site or as soon as feasible and leave a note with contact details if the other party is not present.
Step-by-step explanation:
In the case of a collision causing property damage, injury, or death, you are required to report it on-site if possible or as soon as it's feasible, depending on the severity and circumstances of the incident. Leaving a note with your contact details is also necessary if the affected party is not present to discuss the matter, such as hitting a parked car without the owner nearby. Additionally, it is required by law in most jurisdictions to exchange insurance information and if there are injuries or fatalities, to contact emergency services immediately.
