Vehicles have three different traits; Handling, Acceleration, and Threshold.
Handling: This is the amount subtracted or added from the driver’s Dexterity + Drive draws.
Acceleration: This is the amount they can increase their Speed each turn. It’s either 5, 10, or 15. Successes on a Dexterity + Drive draw add 5 Speed to the normal acceleration.
Threshold: This is the maximum safe speed. If you are traveling over the safe speed, you have a -1 penalty to all Dexterity + Drive draws, with another -1 for every 5 speed you go over this limit.

With mechanical know how, characters can modify vehicles from their base statistics. A vehicle can support a number of modifications equal to the technician’s Handy dots; each modification requires at least four hours’ work to install. Depending on the modification, the Storyteller can require an Intelligence + Handy, Intelligence + Engineering, or Intelligence + Artsy draw. Vehicle modifications will be handled on a case by case basis, but there are some guidelines below.
Potential modifications include:
Smooth: +1 Handling (Can be taken up to 4 times)
Peripherals: A secondary Tool bonus of +1. For example, a masterful paint job which offers a bonus to Persuasion draws, or a hidden compartment for a Stealth bonus. (Can be taken multiple times, choosing a new type of bonus each time.)
Armored: +1 Durability (Takes the space of 2 Modification Slots)
Fast: +5 Acceleration (Takes the space of 2 Modification Slots)
