What does ODO mean in TRANSPORTATION

An odometer is a device used to measure the distance traveled by a vehicle. It records the total distance that has been traversed and is typically found on motor vehicles such as cars, buses, and trucks.

Odometer rollback refers to tampering with an odometer in order to reduce the recorded mileage of the vehicle. This is illegal in many countries as it results in false representation to potential buyers about the true history and condition of the car.

If there are any inconsistencies between the actual physical condition of the car and what is indicated by its reading, this could be an indication that odometer tampering has occurred. Also, unusually low readings compared to other similar models could be suspicious.

Resetting an odometer without proper authorization from local authorities is not recommended as it may be considered illegal depending on local laws. It is best to consult your local laws before making any modifications to your vehicle's odometer. 

Yes, driving at higher speeds will result in a higher reading of distance traveled on your odometer since more ground will be covered in less time.

Most modern vehicles have digital trip meters or electronic displays that keep track of part-time trips taken with them, usually for business or recreational travel purposes. Depending on the type of vehicle you own, it may be possible to reset this meter manually or from within your vehicle’s computer system through a specific procedure provided by the manufacturer.

If your speedometer isn't working properly then you'll need another way to measure your current speed while driving - although you should not drive without a functioning speed gauge installed in your vehicle as it can cause accidents or legal trouble if you exceed posted speed limits unknowingly. You might consider using a GPS device or smartphone app which can accurately record and track speeds up to highway velocities while providing warnings when exceeding posted limits.
