The appropriate actions to take if you need to pull over to the side of the road would include:
- **Check your rear zones and use your turn signal before pulling over.**
This is important for safety to ensure that you do not interfere with other vehicles on the road.
The other options are not generally recommended actions when pulling over:
- Waving down the nearest vehicle for assistance may not be safe, as it could lead to additional hazards.
- Tying a white cloth to the antenna or door handle could be used in some situations as a signal for help, but it is not a standard procedure when simply pulling over.
- Standing to the front of your vehicle can be dangerous, as it leaves you exposed to oncoming traffic.
Thus, the correct action to select is:
- **Check your rear zones and use your turn signal before pulling over.**
