1 Definition of likelihood, consequence and risk levels. We have chosen to use qualitative values for likelihood, consequence and risk levels. 1.1 Likelihood and consequence levels. We decided to use four levels for identification of likelihood and four levels for identification. of consequence. The levels are defined in table 1 and table 2. The likelihood levels can be described as frequency values or with respect to how easy it is. for a person to exploit a threat. For some threats it is easier to think of the likelihood in the. form of frequency or a probability value.
Diesel mechanics repair and maintain large trucks, tractors, and buses. Courses in diesel technology or mechanics are generally found as part of certificate, career diploma, or associate's degree programs available at technical institutes and community colleges.
Smog Information. Currently, smog inspections are required for all vehicles except diesel powered vehicles 1997 year model and older or with a Gross Vehicle Weight (GVWR) of more than 14,000 lbs, electric, natural gas powered vehicles over 14,000 lbs, motorcycles, trailers, or gasoline powered vehicles 1975 and older.OTE: Smog certifications are not required for transfers that occur for a gasoline powered motor vehicle that is four or less model years old. (Determine the oldest-qualifying year model by subtracting three from the current year) the four or less model years old rule does not apply to diesel powered vehicles.
