Escalate the case, not the mood
The step you take should be a function of the record, not of how the conversation went. If the vehicle has no prior notice at this property, it gets a warning, whatever the driver said on the way past.
That rule protects operators as much as drivers. An operator who follows the posted path never has to defend a judgment call.
When a warning is the right call
Almost always, on a first contact. A warning costs the driver nothing and puts the plate, the photos and the rule on the record, which is what the next step rests on.
The warning is also the cheapest way to fix behavior. Most vehicles that receive one never receive a second.
When a citation is justified
A citation is appropriate when the driver has already had notice, or when the violation is a safety matter the posted policy allows to skip the warning step.
Check the record before you escalate. If the earlier warning auto-closed without the vehicle returning, treat this as a fresh first contact unless the policy says otherwise.
When immobilization is warranted
Immobilization is one tool inside the system, not the definition of it. It is warranted for repeat violations or unresolved citations, where a fee alone has demonstrably not changed the outcome.
It is never a first response, and it is never appropriate where a tow is the safer option, such as a vehicle blocking emergency access.
Handing off to a tow partner
A tow is an escalation of the same record, not a new one. The partner receives the plate, the vehicle, the payment state, the property, the pickup address and the yard rules already attached.
The system will not let a bad release through: unpaid citations in that zone block Pickup Completed until they clear.
Documenting so the record answers for you
Three photographs, every time. Pre, plate, post. They take twenty seconds and they end most disputes before a person has to read anything.
Write notes as facts, not conclusions. "Blocking the fire lane, owner not on site" is useful six months later. "Driver was rude" is not.
