### <a name="YawRateConfidence"></a>YawRateConfidence
 This DE denotes the absolute accuracy range for reported yaw rate value for a confidence level of 95%.
 
 The value shall be set to:
 - `0` indicates that the accuracy is equal to or less than 0,01 degree/second.
 - `1` indicates that the accuracy is equal to or less than 0,05 degrees/second.
 - `2` indicates that the accuracy is equal to or less than 0,1 degree/second.
 - `3` indicates that the accuracy is equal to or less than 1 degree/second.
 - `4` indicates that the accuracy is equal to or less than 5 degrees/second.
 - `5` indicates that the accuracy is equal to or less than 10 degrees/second.
 - `6` indicates that the accuracy is equal to or less than 100 degrees/second.
 - `7` indicates that the accuracy is out of range, i.e. greater than 100 degrees/second.
 - `8` indicates that the accuracy information is unavailable
 
 NOTE: The fact that a yaw rate value is received with confidence set to `unavailable(8)` can be caused by
 several reasons, such as:
 - the sensor cannot deliver the accuracy at the defined confidence level because it is a low-end sensor,
 - the sensor cannot calculate the accuracy due to lack of variables, or
 - there has been a vehicle bus (e.g. CAN bus) error.
 In all 3 cases above, the reported yaw rate value may be valid and used by the application.
 
 If a yaw rate value is received and its confidence is set to `outOfRange(7)`, it means that the reported
 yaw rate value is not valid and therefore cannot be trusted. Such value is not useful the application.

### <a name="YawRateValue"></a>YawRateValue
 This DE represents the vehicle rotation around z-axis of coordinate system centred on the centre of mass of the empty-loaded
 vehicle. It corresponds to the vehicle coordinate system as specified in ISO 8855 [2]. The leading sign denotes the direction of rotation.
 
 The value shall be set to:
 - `-32 766` to indicate that the yaw rate is equal to or greater than 327,66 degrees/second to the right.
 - `n (n > -32 766 and n <= 0)` to indicate that the rotation is clockwise (i.e. to the right) and is equal to or less than n x 0,01 degrees/s, 
      and greater than (n-1) x 0,01 degrees/s.
 - `n (n > 0 and n < 32 766)` to indicate that the rotation is anti-clockwise (i.e. to the left) and is equal to or less than n x 0,01 degrees/s, 
      and greater than (n-1) x 0,01 degrees/s.
 - `32 766` to indicate that the yaw rate is greater than 327.65 degrees/second to the left.
 - `32 767` to indicate that the information is not available.
 
 The yaw rate value shall be a raw data value, i.e. not filtered, smoothed or otherwise modified.
 The reading instant should be the same as for the vehicle acceleration.
